BACKYARD BIODIVERSITY OUR NATURE: BUTTERFLIES 1 If you have a backyard, courtyard or a balcony you have the opportunity to support our native plants and animals by providing habitat for our diverse native wildlife. ECOSYSTEMS DIVERSITY Essential for a healthy planet SPECIES DIVERSITY Backyards are an important part of the Gold Coast’s natural landscape with more than half of the city’s native vegetation on private properties. Essential for healthy ecosystems Our native plants and wildlife are essential to our environmental, social and economic health and wellbeing. GENETIC DIVERSITY The Gold Coast is one of the most biodiverse cities in Australia. Essential for healthy species Backyard Biodiversity 1 Threatened species Biodiversity is reduced when species become extinct. Plant and animal species which are at risk of extinction are known as threatened species. Threatened species can be identified by their conservation status which is specified under both Federal [Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act)] and State [Nature Conservation Act 1992 (NC Act)] legislation. A range of factors is used to assess a species’ conservation status including: • • • the number of individuals remaining the overall increase or decrease in the population over time breeding success rates and known threats. While the categories and specific definitions used differs between State and Federal legislation, in both cases the status indicates whether a species still exists and how likely it is to become extinct. Gold Coast On the Gold Coast, species which are locally significant are known as City-wide significant (CWS) species. These species are important because they may be threatened, restricted to the Gold Coast, or at the edge of their geographic range. CWS You and your backyard can contribute to supporting threatened and CWS species by creating and restoring habitat in your backyard. Throughout this booklet, Threatened, Near threatened and CWS species are identified using the symbols shown below. They are accurate at the time of printing.

Often brilliantly patterned and coloured, they enhance our gardens, parks and bush – appearing like living flowers as they flit from plant to plant Australia is home to almost searching for nectar. Some are familiar to everyone: the 400 robust orange and black Wanderer is active all year; the different species of butterflies black and white Crow butterfly thrives on exotic plantings The Gold Coast is, or has been, home to as many as 170 species of butterflies of oleander; the tiny blues that flitter around every lawn; and the few species that eat things we’d rather they didn’t. Around the world, populations of many species have declined or even disappeared under the frantic pressure of urban development. Only a very few species, such as the Common Crow and Cycad Blue, have benefitted from human modifications of the environment and are now relatively common in urban areas. The first meal of a caterpillar is frequently its own EGGSHELL Butterflies are closely linked to the HOST PLANTS that their caterpillars eat. Take action in your backyard • Protect and restore natural bushland. • Grow butterfly host plants. • Grow nectar plants. • Maintain or create wet areas for ‘mud puddling’. • Avoid using pesticides. Some species of butterfly DEPEND ON ANTS which look after their caterpillars. BACKYARD BIODIVERSITY: Our Nature – Butterflies Some species of butterfly absorb POISONOUS chemicals from the plants on which their caterpillars feed. 5 About Butterflies Butterflies and moths belong to the huge group of insects collectively known as the Lepidoptera – that is insects that, as adults, have wings covered in overlapping scales. It is these scales that carry the bright and not so bright colours and patterns by which most of the 180,000 described species worldwide are distinguished. Did you know? Lepidoptera is from the Greek words ‘lepidos’ meaning scale and ‘pteron’ meaning wing. Globally, butterflies range in size from just a few millimetres (our Tiny Grass Blue can lay claim to being among the very smallest with a wingspan of as little as 10mm) to the giant birdwings of New Guinea (the female Queen Alexandra Birdwing has a wingspan of up to 300mm). Our largest, locally occurring butterfly is the Richmond Birdwing, the females of which have a wingspan up to 120mm. Many adult butterflies have different wing patterns between the sexes which, in the past, often led to them being identified as separate species. Examples include the Richmond Birdwing, the Orchard Swallowtail and the Common Eggfly. A few species have different colour forms in different seasons. Almost always, the colours and patterns of a butterfly’s upper wings contrast with those on the underside. The colours of the upper wings are involved in mate recognition and signalling, whereas the underside colouration is often a matter of blending into the background when at rest. For several groups of butterflies, the patterns on the underside are the most useful feature for identifying the species. The butterflies we see flying are the endpoint of a complex life-cycle that can span many months. Throughout this life cycle, the lives of butterflies are inextricably linked with plants: indeed, it is generally supposed that the butterflies and flowering plants evolved together, developments in one group impacting on the other, and vice-versa. Evening Brown (Melanitis leda) BACKYARD BIODIVERSITY: Our Nature – Butterflies 7 The life cycle Life cycle - White Nymph (Mynes geoffroyi) We are most familiar with adult butterflies. Adult butterflies are the fourth and final of the life stages through which each and every species of butterfly must pass. Unlike many species of butterfly, the caterpillars and chrysalises of White Nymphs are often found in groups. Stage 1 – egg Their lives begin as eggs deposited on plants by female adult butterflies after they have mated. These eggs are generally small, globular or ribbed and may be laid singly or in clusters. 1 Stage 2 – caterpillar (larva) From the eggs emerge caterpillars (larvae) which generally are the longest stage of the insect’s life. With just a very few exceptions these caterpillars eat the leaves of plants. Some species, like the Richmond Birdwing (Ornithoptera richmondia), have a highly specialised diet and only one or two species of host plants will do. For others, like the Common Eggfly (Hypolimnas bolina) or Blue Triangle (Graphium sarpedon), a wide range of plant species are acceptable to the caterpillar – although these plants are often closely related. The caterpillars grow dramatically during their lives, casting off their skins (moulting) to allow them to grow at least four times. With the last of these moults, the caterpillar shortens and thickens before transforming into the third life stage, the chrysalis. 2 1 Female butterfly laying eggs 2 Caterpillars 3 Chrysalises 4 Adult butterfly recently emerged from chrysalis 4 3 BACKYARD BIODIVERSITY: Our Nature – Butterflies 9 Stage 3 – Chrysalis (pupa) Ecological Role The chrysalis or pupa is perhaps the most remarkable of the four stages. Butterflies and moths (like beetles, flies and bees) undergo a process known as complete metamorphosis. During the pupal stage, most of the tissues and cells of the larva break up and are re-assembled into the dramatically different adult shape. It is within the pupa that the butterfly’s wings develop. Butterflies, in all stages of their life cycle, play important roles in our ecosystems. Adult butterflies pollinate flowers. Their eggs and caterpillars are a vital part of ecosystem food chains, providing food resources for a wide range of predators and parasites including birds, dragonflies, wasps and spiders. Stage 4 – Butterfly After a few weeks or months, the chrysalis case splits and the adult butterfly emerges, its wings expanding, drying and hardening in the air. Adult butterflies need three things in life: energy resources to fuel their flight – principally nectar from plants but sometimes rotting fruit or even animal dung; they need water to prevent them desiccating (drying out) from the sun’s rays; and they need a mate. Most species mate only once and the male products are stored within the female ready to fertilise each egg when it is mature and ready to be laid. There are a fascinating range of mechanisms by which males and females find each other, evaluate the ‘quality’ of the potential mate, and where males try to prevent others from mating with the same female. Caterpillars are particularly important. They are relentless eating machines, transforming the tissues of their host plants into body mass. Without plant eaters like caterpillars, the energy of the sun captured by plants would not be released to the wider world. Butterflies and moths are one of the principal groups of animals which make this release happen and as a result they are a driver of ecosystems. This crucial role is often overlooked when we try to prevent our plants at home from being eaten – without that release of energy by caterpillars, our environment and its biodiversity is reduced. Because butterflies are sensitive to changes in our climate and respond quickly to environmental stress, they are good indicators of an ecosystem’s wellbeing. An abundance of butterflies usually indicates a healthier ecosystem. It is the female butterflies who seek out appropriate host plants and deposit mature eggs on or close to these plants. SO THE LIFE CYCLE BEGINS AGAIN. Black Jezebel (Delias nigrina) caterpillars feeding on mistletoe species BACKYARD BIODIVERSITY: Our Nature – Butterflies 11 Butterflies and Ants Ants are usually considered to be very general predators mopping up anything in their path, alive or dead. However, for some blue butterflies in the family Lycaenidae, ants don’t prey on them, they work with them. These butterflies have evolved to allow ants to care for their caterpillars, protecting them from other predators like wasps and parasitic flies – and from other ants. In return, the caterpillars provide chemical and food rewards which the ants ‘milk’ from specially-evolved glands. The Gold Coast is home to at least 24 species of butterfly that have evolved these mutualistic relationships with ants. Often this is with a very particular species of ant – and where that sort of ant isn’t present, then the butterfly is also likely to be absent from that location. Sometimes the relationship is casual, with just a few ants riding on the backs of the caterpillar: in other cases, it is so intense that it is easier to search on a plant for a mass of ants which will be completely covering a caterpillar, than to look for the caterpillar themselves. In some cases these ant-friendly caterpillars shelter inside the ants’ nests. One small group of butterflies have totally turned the tables on the ants. They have become predatory on the ant larvae in the nest. One of our rarest Gold Coast butterflies, Illidge’s Ant Blue (Acrodipsas illidgei), is one of these predatory species. Did you know? A mutualistic relationship is where two different species have an ongoing, long term relationship which benefits both species.

In Australia, the greatest diversity is found in tropical north Queensland where many species thrive in the warm humid air of tropical rainforests. The Gold Coast is in an area where many butterflies typically found in north-eastern Australia and those found in south-eastern Australia converge, as a result our butterfly diversity is also quite high. A few species fly long distances. Others don’t venture far from their host plants. Some are highflyers and will be found in the canopy of trees where their host plants such as mistletoe or vines grow. Others stick close to the ground amongst the grasses and legumes of the understorey or open ground. Behaviour Butterflies are cold blooded. This means that they must absorb heat to become active. To absorb heat they often take up basking positions on plants, rocks or bare patches of soil. Conversely, if conditions become too hot they run the risk of drying up through dehydration and will rest in shady positions. In South East Queensland, some species are active as adults all year round. Nevertheless, there are seasonal differences and only a few species will be encountered in the winter months. The arrival of spring sees the emergence of many more species which often then complete a further generation over the summer leading to a second, often larger, emergence in February and March. These general patterns may change in times of environmental stress, such as during extended droughts. Some butterflies are considered to be migratory or irruptive (many occurring together) with large numbers of butterflies moving together, sometimes across long distances. These migrations facilitate widespread pollination which contribute to improved plant health and genetic diversity. Local migratory butterflies include: Caper White Belenois java Breed in the drier inland with caterpillars common on pepper bushes (Capparis spp.). In spring ‘excess’ adults, often in their thousands, move eastwards to coastal regions and out to sea. BACKYARD BIODIVERSITY: Our Nature – Butterflies Blue Tiger Tirumala hamata Mass movements southwards each summer to seek nectar on flowering shrubs such as paperbarks. Even though its larval food plant, the corky milk vine (Secamone elliptica) occurs widely, it probably breeds only occasionally, if at all, in our region. 15 Butterflies of the Gold Coast The Gold Coast is, or has been, home to as many as 170 species of butterflies supported by the many vegetation communities found here. Different butterflies occur from the tidal wetlands and swamp forests on the coast, through the dry and wet eucalypt forests of the foothills and into the rainforests and montane heath of the mountains in the hinterland. Some butterflies only occur in one vegetation community. On the Gold Coast more than 50 species of butterflies, including Macleay’s Swallowtail (Graphium macleayanum), Narrow-winged Pearl White (Elodina padusa) and Bright Forest Blue (Pseudodipsas cephenes), are only found in rainforest. As their names imply, Saltbush Blue (Theclinesthes serpentata) and Samphire Blue (Theclinesthes sulpitius) are found on salt bushes and samphires of our tidal wetlands. The Hyaline Swift (Parnara amalia), Grey Swift (Parnara bada) and Swordgrass Brown (Tisiphone abeona) are restricted to swamp forests and freshwater wetlands where the wetland grasses and sedges that are their host plants grow. Many inhabit forest and woodland edges. They need natural or artificial clearings to find mates and to find particular host plants such as herbs and scrambling vines, which are often species of disturbed areas. Others are found only high in tree canopies where their host plants such as mistletoe and vines grow. Some are at home in our gardens and parks. Examples of local butterflies have been included in this booklet. Throughout this booklet the following symbols are used to indicate the typical habitat, behaviour and abundance of the butterflies described. Vegetation community - see map on page 41 for the historic distribution EC TW C SF FW RA E WE Exposed Coastal – Coastal dunes and rocky headlands. Typically dominated by grasses with wind shorn shrubs and trees (e.g. coastal banksias and she-oaks) inland from the shore. Tidal Wetlands – Mangrove, salt marsh and swamp oak vegetation communities associated with tidal flats within estuaries. Mistletoes often occur in tree canopies. Coastal – Protected coastal areas. Includes open woodlands and heathlands (wallum). Flowering shrub component includes tea trees, banksias, peas, wattles and grasstrees. Swamp Forest – Lowland coastal areas regularly inundated by freshwater or with areas of standing water. Typically dominated by Melaleuca species. Freshwater Wetlands – Areas subject to prolonged periods of freshwater inundation. Plants are predominantly aquatic or semi- aquatic sedges, rushes and similar plants. Riverine and Alluvial – Forest and woodlands which occur on alluvial banks and plains adjacent to waterways. May be periodically subject to flooding. May include rainforest species when fire is excluded for long periods. Eucalypt – Dry eucalypt forests and woodlands. Understorey plants include wattles, she-oaks, peas, grasstrees, herbaceous wildflowers and grasses. Mistletoes often occur in tree canopies. Wet Eucalypt – Wet eucalypt forests and woodlands. Due to higher soil moisture and longer intervals between fires, rainforest trees and shrubs occur along with vines, ferns and sedges. RF MT Rainforest – Complex dense forests typically with closed canopies and an array of plant life which can include vines, mosses, ferns, palms, strangler figs and epiphytes. Montane – Occurs on mountains either as heath communities on expanses of rock or as small isolated outcrops of vegetation on rock shelves and in crevices of cliff faces. Butterfly is associated with grasslands and grassy understories. Butterfly commonly occurs in parks and gardens. Abundance Common – Species that are seen daily in suitable habitat during their flight season. Uncommon – Species that may be seen in suitable habitat at least once each flight season. Rare – Species not necessarily seen in suitable habitat every flight season. Local – Species which are restricted in their distribution but at times common in those places. Behaviour Migratory or irruptive – large numbers of butterflies moving together. Specialist – Utilises only one or two host plant species. Caterpillars eats plants which contain poisonous chemicals which deter predators.

Australia hosts 18 species in this family, of which ten may be found on the Gold Coast. Butterflies in this family exploit a wide range of host plants. Species from the family Papilionidae that occur on the Gold Coast include: Four-barred Swordtail Protographium leosthenes Macleay’s Swallowtail Graphium macleayanum RF Caterpillar feeds on the rainforest zig-zag vine (Melodorum leichardtii).

Caterpillars feed on a range of legumes such as Emu Foot (Cullen tenax). Orchard Swallowtail Papilio aegeus E WE RF Native habitat rainforest, rainforest edges and other moister habitats. Caterpillars feed on a wide range of native and introduced plants, mainly of the citrus family (Rutaceae). Big Greasy Cressida cressida E Caterpillars feed on a number of small species of poisonous Aristolochia vines which grow amongst grass and other lowgrowing vegetation. 19 The Richmond Birdwing: a conservation success story The group of Asian and Australian butterflies known as the Birdwings include the biggest butterflies in the world. Although we cannot claim that accolade for our species, the Richmond Birdwing (Ornithoptera richmondia) is certainly the biggest of our local butterflies. It is also the only Birdwing butterfly found outside the tropics. By 2013 the program had enjoyed considerable success not least through the substantial involvement of volunteers through a welldesigned campaign of public awareness. You can help the Richmond Birdwing by planting its host plants. Once distributed from Grafton to Maryborough, the butterfly declined through the 20th century as its rainforest habitats were destroyed, degraded or fragmented. By the end of the last century, the butterfly was only found as scattered, genetically isolated, populations on the Sunshine Coast and the Gold Coast. On the Gold Coast, populations remained, occasionally numerous, in the rainforests of the hinterland but numbers fluctuated wildly from year to year. The Richmond Birdwing has very specialised caterpillar feeding habits. It seeks out mature Birdwing Vines (Pararistolochia praevenosa) in its lowland range and the Mountain Aristolochia (Pararistolochia laheyana) in its upland habitats. Occasional severe winters in upland habitats may substantially reduce the numbers of this species. The species was declared Vulnerable in Queensland in the 1980’s and a Draft Recovery Plan developed in 1996. Since then, intensive efforts and resources have been brought to bear on the species’ conservation including extensive planting of the vines, removal of other toxic, introduced vines (related to but not the same as the preferred host plants), captive breeding and release, and attempts through habitat management to develop connecting corridors of suitable habitat to overturn the genetic isolation which had arisen during the species’ decline. Richmond Birdwing (Ornithoptera richmondia) BACKYARD BIODIVERSITY: Our Nature – Butterflies V 21 FAMILY: PIERIDAE THE WHITES, YELLOWS AND JEZEBELS The family Pieridae includes some of our most familiar species. Australia hosts about 35 species of which 18 may be encountered locally. The whites and yellows can be difficult to identify as many species have different seasonal forms. However, the brightly coloured jezebels are beautiful and distinctive. Many species in this family have adapted to larval host plants, such as mistletoes and plants in the cabbage family, which make the adult butterflies distasteful to predators. Caper Gull Cepora perimale E WE RF Common larval host plants are species of Capparis. Small Grass Yellow Eurema smilax E Occur, irregularly, sometimes in very large numbers. Caterpillar host plants are both native and exotic species of the yellow-flowered shrubs, Cassia and Senna species. C E WE One of the most common of the local grass yellows. Active all year. Caterpillar host plants are a wide range of low growing legumes including Cassia and Senna species. BACKYARD BIODIVERSITY: Our Nature – Butterflies Black Jezebel Delias nigrina SF E WE A cool season species that is found in mountains in summer and in coastal areas in autumn and winter. Host plants are species of mistletoe. SF RA E It favours swamp forests where adults are often found on Melaleuca blossoms. Its host plants include a number of species of mistletoes. Species from the family Pieridae that occur on the Gold Coast include: Lemon Migrant Catopsilia pomona Scarlet/Northern Jezebel Delias argenthona RF Southern Pearl-white Elodina angulipennis RF Often found in the subcanopy of rainforests. Local host plants are Capparis spp. 23 FAMILY: LYCAENIDAE THE BLUES, COPPERS AND HAIRSTREAKS The Lycaenidae are the largest and most diverse family of butterflies worldwide with over 6000 named species. Across Australia we have about 140 species and about 57 are found within the Gold Coast region. The most familiar blues are the several tiny species found in and around urban and semi-urban lawns and gardens. Bush gardens, woodlands and forests contain much more dramatic species whose well-being often depends on their symbiotic relationships with specific species of ants. Species from the family Lycaenidae that occur on the Gold Coast include: Copper Jewel Hypochrysops apelles E E WE Prefers disturbed dry woodlands with an abundance of young wattle plants. Caterpillars are always attended by ants (Iridomyrmex spp.). BACKYARD BIODIVERSITY: Our Nature – Butterflies C WE One of the smallest butterflies in the world. Local larval host plants are small herbaceous plants Hygrophila angustifolia. Caterpillars are occasionally attended by small ants. Yellow-spotted Blue Candalides xanthospilos EC Tiny Grass Blue Zizula hylax E Widespread and locally common. Host plant - Oxalis spp. Caterpillars are always attended by ants (Iridomyrmex spp.) and pupate in ant nests. Common Imperial Blue Jalmenus evagoras TW Occurs in tidal wetlands where its mangrove host plants occur. Caterpillars are always attended by ants (Crematogaster spp.). Small Copper Lucia limbaria E Occurs in coastal vegetation communities with heath understories where its larval host plants Pimelea spp. (rice flowers) occur. Samphire Blue Theclinesthes sulpitius TW Common in tidal wetlands. Larval host plants are samphires - succulent, herbaceous plants which grow in high salinity environments of tidal areas. 25 FAMILY: HESPERIIDAE THE SKIPPERS Australia hosts about 120 species of skipper and as many as 50 may be found on the Gold Coast. They occur in all terrestrial ecosystems. Most are inconspicuous, small, and orange and brown, although there are some large spectacular species. They have a very distinctive way of perching with the wings partly open – the so-called ‘jet-fighter’ position. Species from the family Hesperiidae that occur on the Gold Coast include: Regent Skipper Euschemon rafflesia RA SF RA WE Caterpillars live and feed on the foliage of many species of native and exotic palms. Local host plants include the Bangalow Palm and Cabbage Tree Palm. BACKYARD BIODIVERSITY: Our Nature – Butterflies WE RF Green Awl Hasora discolor RF Largest Ochre. Host plant is Lomandra longifolia which is common in parks and gardens. Other Lomandra species sometimes used – L. filiformis, L. hystrix, L. obliqua and L. spicata. Orange Palm-dart Cephrenes augiades RF Occurs in rainforests. Caterpillars feed on the foliage of Wilkiea species which are shrubs/ small trees that grow in rainforest understorey. Splendid Ochre Trapezites symmomus RF Local but not often seen. Its caterpillar makes a shelter by cutting and folding the leaves of its local host plant Burny Bean (Mucuna gigantea). Orange Grass-dart Suniana sunias SF FW Found in vegetated swamps and freshwater wetlands where its native host plant Swamp Ricegrass (Leersia hexandra) grows. Painted Sedge Skipper Hesperilla picta C E WE Usually found in sheltered gullies. Like most sedge skippers its host plant is a saw-sedge. In this case, Tall Saw-sedge (Gahnia clarkei). 27 FAMILY NYMPHALIDAE BRUSH-FOOTED BUTTERFLIES This family – the so-called brush-footed butterflies because the first pair of legs in the adult butterflies are reduced to mere stubs – rivals the Lycaenidae in numbers of species. It contains a very wide diversity of species which range from the brightly coloured milkweed butterflies and admirals through to the rather plain ‘browns’. In the Gold Coast region we have about 33 of Australia’s total of 81 species. Species from the family Nymphalidae that occur on the Gold Coast include: Common Crow Euploea core SF E WE Occurs in a wide range of habitats. Its caterpillars feed on monkey-rope vine (Parsonsia straminea) and related species. The adults may live for many months accumulating in large roosts over the dry months. RF Black and White Tiger Danaus affinis TW TW C RA E A distinct Australian species, this butterfly looks like a miniature version of the exotic Wanderer butterfly. Caterpillars feed on local vines such as Vincetoxicum spp. and Marsdenia spp. BACKYARD BIODIVERSITY: Our Nature – Butterflies WE C C Its caterpillar feed on Mangrove Wax-flower vine (Vincetoxicum carnosum) which sprawls within grasses on the edges of mangroves and marshy coastal areas. Lesser Wanderer Danaus petilia Swordgrass Brown Tisiphone abeona As its name suggests this butterfly depends on the saw-sedges (Gahnia spp.) for its wellbeing and its caterpillars feed only on this group of plants. Evening Brown Melanitis leda C RA E WE A shade-loving species that lives close to the leaf litter. It has two distinct, seasonally driven colour forms – a darker wet season form and paler dry season form. Caterpillars feed mainly on grasses. RF RF Common Eggfly Hypolimnas bolina E WE RF Host plants are low growing herbaceous ground covers such as Alternanthera spp. Pseudoranthemum spp. and Sida spp. 29 The Australian Fritillary – Gone for ever? Legal protection cannot preserve this, or any other butterfly species, without constant vigilance and intervention, which requires intimate knowledge of species’ biology. Modern humans have so modified the landscape, especially of our coastal lowlands, that simply designating areas as reserves will not always work. For our rarer and more particular species, like the Fritillary, maintaining vegetation, soil and water regimes will be essential if we are to keep these species for the future. Climate change will make this an even more challenging task. The Australian Fritillary (Argynnis hyperbius inconstans) is, or probably was, one of our most spectacular butterflies. It is our only species of Fritillary – a large group of mostly northern hemisphere butterflies. It occurred from Gympie, south along the coast to just north of Port Macquarie. Known occurrences in the Gold Coast included Coolangatta and Burleigh Heads. Mountain Birdwing Vine Arrow-leaved Violet The Fritillary preferred disturbed Viola betonicifolia wetlands with rich, moist soil where its larval food plant, the arrow-headed violet (Viola betonicifolia) preferred to grow. The plant is still found in our region, but the particular set of circumstances which sustained the Fritillaries seem to have disappeared. It has been described as a ‘Goldilocks Species’ for which environmental conditions had to be ‘just right’. The Australian Fritillary has not been seen in the Gold Coast since the early part of the twentieth century. If it survives in Australia at all, it is likely to be at remote sites around Limeburner’s Creek north of Port Macquarie, NSW. But even there, the species has not been seen since 2001. E CE Australian Fritillary Argynnis hyperbius inconstans BACKYARD BIODIVERSITY: Our Nature – Butterflies 31 Exotics and Pests Take action in your backyard Australia has only two exotic butterflies: that is, species introduced to the continent by European settlement. Both species are common on the Gold Coast. These are the Cabbage White and the Wanderer (known elsewhere as the Monarch). Butterflies are an essential part of our environment, delighting us with their passing beauty. They are also essential to the healthy functioning of our gardens, parks and bushland. As human pressures mount – on land area and on native vegetation – these benefits will only persist if we are proactive in both protecting and enhancing our environment for butterflies. A small number of native species are occasional low level pests. Only one of these, the Cycad Blue, impacts on horticulture in our region. Keep it local EXOTIC Wanderer Danaus plexippus Known elsewhere (and to a lesser extent in Australia) for its regular long distance migrations, the species was first recorded in Australia in the 1870s. It is now common over the entire eastern seaboard with a satellite population established around Perth. Not regarded as a pest. NATIVE Cabbage White Pieris rapae Originated in Eurasia but now found worldwide. It arrived, probably via New Zealand, in Australia in 1939. A significant pest for growers of cabbages and other brassicas. BACKYARD BIODIVERSITY: Our Nature – Butterflies Cycad Blue Theclinesthes onycha The one overriding principle for protecting and enhancing habitat for butterflies is to keep it local. To re-establish themselves, butterflies must come from somewhere. A few species can fly long distances and will likely turn up in any halfsuitable place, but most are likely to spread out gradually from adjacent established habitat. Don’t expect rainforest butterflies to appear in your backyard if it is distant from the nearest natural area of rainforest – even if you’ve nurtured or planted the ‘right’ host and nectar plants. Historically a rare native butterfly that was found only in moister eucalypt woodlands that had cycads. Due to the popularity of ornamental cycads it has become a slight inconvenience to gardeners as the caterpillars shred the soft new fronds of planted cycads as they elongate. 33 Protect and restore areas of native vegetation First we must protect the remaining areas of natural bushland in our backyards and landscapes. These natural areas are homes to many species of butterfly – every time a patch of bush is cleared, however small, it reduces the world for butterflies and other biodiversity. Butterflies will thrive in natural bushland if left alone. Protected areas for butterflies do not even need to be very large, although there are many other reasons why larger reserves are required. There are well-established practices for restoring natural bushland (see the Want to Know More section on page 70 for information and resources) but restoration practices can be more or less friendly to butterflies depending on how they are done. Some local butterflies which utilise mistletoes as host plants include: Diggles’ Jewel Hypochrysops digglesii Satin Azure Ogyris amaryllis Trident Pencil-blue Candalides margarita Marbled Line-blue Erysichton palmyra Don’t mess with the mistletoe Mistletoes are native plants that grow on other plants. Because they are parasitic (take water and nutrients form their host plant) they are often thought to be a problem. In fact, it is quite the opposite. Mistletoes play a vital role in ecosystems and support a wide range of animals including butterflies. In addition to their flowers providing nectar, they are also host plants for more than 10 species of butterflies on the Gold Coast – let them grow! BACKYARD BIODIVERSITY: Our Nature – Butterflies Amyema pendulum – grows on several species of eucalypt. 35 Clear flowering weeds in stages Adult butterflies need flowering plants to provide the nectar they require as fuel. Clearing all flowering ‘weeds’ from a plot under restoration may initially discourage butterflies from re-establishing, but natives will soon begin to regenerate in their place. It’s recommended that weed control be done in stages, allowing native nectar sources to naturally regenerate as the weeds are removed. Gardens for butterflies need to provide two plant types: caterpillar host plants and flowering plants for nectar. Other resources needed by some species – like particular ant species – are hit-and-miss affairs in a garden and these species will probably best thrive in natural ecosystems. If they do turn up in a garden, you should regard that as an incredibly lucky win for biodiversity. Maintain or create edges Forest and woodland edges are essential for many species of butterflies. They need natural or artificial clearings to find mates and to find particular host plants (which may often, themselves, be species of disturbed areas, like many herbs and vines). Be patient Butterflies will not return immediately. Remember, some require mature foliage, or flowers and fruits, for their caterpillars to thrive. Others require vines or mistletoes which will only thrive once other plants are established. Create butterfly habitat Gardens are special cases for the butterfly conservationist. If your garden abuts natural bushland then many of the principles of restoration apply. However, no matter where your backyard is, you have the opportunity to create a butterfly habitat which may be unlike any natural environment, yet still be a place in which our native butterflies can thrive. BACKYARD BIODIVERSITY: Our Nature – Butterflies Common Crow courtship – the male above dusts the female with pheromones from his hair-pencils 37 Grow butterfly host plants Throughout their life cycle, the lives of butterflies are inextricably linked with plants. Adult butterflies feed on the nectar of flowers and even more critically, they need host plants to lay their eggs on and for their caterpillars to eat. As noted previously, some species of butterfly are highly specialised and their caterpillars rely on one or two species of host plant. For other butterflies, a wide range of host plants are acceptable – although these plants are often closely related species. Attract a variety of butterflies by growing a variety of host plants. Some plants – like softer-leaved wattles (Acacia spp.), the tuckeroo (Cupaniopsis spp.), flame and bottle trees (Brachychiton spp.), tulipwood (Harpullia spp.), native citrus (Citrus spp.), indigofera (Indigofera spp.), mat rushes (Lomandra spp.) and native grasses (various) – are very hardy and can support a wide range of butterfly species, so are obvious choices. If you have a bush garden, be sure to leave a few plants which you might otherwise remove, such as nettles, some vines, sennas and cassias. These will attract butterfly species whose caterpillar live on few other plants. Local native plants are preferred – even though non-native substitutes will attract a few butterfly species. Butterfly Garden - Gold Coast Regional Botanic Gardens BACKYARD BIODIVERSITY: Our Nature – Butterflies 39 Local Native Plants Local native plants are those that occur naturally in a location. Native vegetation grows in groups of local native plants and these groups vary depending on local conditions such soil, landform, aspect and climatic features such as rainfall. See key on pages 42 – 43 When selecting the most suitable local native plants for your backyard it is useful to understand the native vegetation group which grows on your property, or has grown in the past. It is also important to understand the type of vegetation community re-establishing butterflies might come from. When you plant the right local native plant in the right place, you save time, money, effort, energy and you do less maintenance. You also create the most appropriate habitat for local butterflies. This map shows the historic location of vegetation groups found on the Gold Coast. Find the vegetation group that grows where you live. You can then choose local native host plants from this group to grow in your backyard by looking for the matching colour code in the local native plant list on pages 45 to 66.

pauli-guilielmi WE E E RF To attract butterflies to your garden, you also need to provide nectar plants for the adults to feed from. In this regard butterflies are rather unspecialised. They will go for any flower that provides nectar rewards they can reach with their ‘drinking straw’ tongues. Bright UV-rich colours such as red, white and purple are preferred, but any rich, accessible source of nectar will be used. Basically any freely available open-faced flowers will attract butterflies. Tubular flowers may be particularly attractive as long as the butterflies can reach the nectar sources deep inside the flower tubes.

Many non-native flowering plants are also exploited, just remember to avoid complex artificially bred ‘doubles’ and those that have been bred for appearance rather than biological fitness. These are likely to produce little or no nectar and scent and do not provide butterflies with a food source. Create moist areas for ‘mud puddling’ In a dry climate, butterflies will also seek out patches of moist ground to indulge in what is called ‘mud-puddling’. They suck water from the ground, pass it through their bodies and absorb nutrients, and no doubt some water. You can support butterflies by creating wet areas lined with gravel and/or stone where they and other insects can safely access water without drowning or getting stuck in mud. Reduce the use of pesticides Like all insects, butterflies are highly sensitive to pesticides. Reducing or stopping the use of pesticides in the garden can benefit butterflies and many other kinds of ‘useful’ insects. Don’t assume that because a product is on sale it is not harmful to native species.

Ecological restoration undertaken by a private landholder Bushland restoration Ecological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed. It involves activities such as weed control, erosion control, exclusion of grazing animals and management of pest animals. More information about how to undertake ecological restoration on your property can be found on the City of Gold Coast website by searching for the following: • South East Queensland Restoration Framework: Details a framework for undertaking ecological restoration and includes a manual which provides a technical, but easy to use, guide to all aspects of ecological restoration. • Environmental Weeds and Invasive Plants: Information about identifying and managing environmental weeds. • Ecological Restoration Techniques: Suite of videos demonstrating best practice weed management and other restoration techniques. • Landholder Partnerships: Details services provided to assist private property owners with restoration and conservation of their land including Land for Wildlife, Voluntary Conservation Agreements and Bushland Health Checks. BACKYARD BIODIVERSITY: Our Nature – Butterflies MAY 2014 OCTOBER 2014 JUNE 2016 MAY 2018 71 Local native plants Purchasing plants that are local provenance is an important contribution you can make to the environment. Local provenance means that the plant is grown from local, naturally occurring specimens. Planting these, rather than plants sourced from far afield, preserves the local gene pool of that species. It also supports local native plant nurseries, which play a vital role in contributing to the greening of the city and supporting the local economy. Where to buy local native plants Use the GroNative App to find nurseries in South East Queensland that stock plants listed in the app. Search for suppliers and native plant sale events online: • Native Plants Queensland has autumn and spring plant sales which are a great way to buy interesting and hard to find native plants. Nurseries are listed on their website. • The Australian Native Plants Society website provides a list of native plant nurseries. • Gardening events and shows are held regularly on the Gold Coast and across South East Queensland. • There are a number of online plant suppliers which you can find by searching for plants by species names. Visit the Friends of the Gardens nursery at the Gold Coast Regional Botanic Gardens. The nursery stocks a wide range of local native plants and is open from 8 – 11am on the first Friday of each month.
