Examples of Insects ; Bee Ant Butterfly House Fly Characteristics ● It is a small arthropod animal ● Segmented body into three parts ● Has six legs ● Generally 2-3 pairs of wings (midges & mosquitoes have one pair of wings) ● Have three pairs of jointed legs ● Have one pair of antennas ● Have a exoskeleton ● Compound eyes Adaptation ● Move about by walking, flying and sometimes swimming ● Are mostly solitary (like to live alone) ● Insects like bees, ants and termites live in well-organized large colonies ● They are mainly terrestrial ● They can live in very dry places because their exoskeleton and trachea are very good at stopping water from evaporating from the insect’s body an ant colony Nutrition ● Insects eat in many different ways and they eat a huge range of foods. ● Around half are plant-eaters, feeding on leaves, roots, seeds, nectar, or wood. ● Aphids and leafhoppers suck up the sap from plants. Sensitivity ● Most insects have one or more sensory organs that are sensitive to vibrations transmitting through the air. ● Some insects even listen for the sounds of predators in order to avoid being eaten by them. ● All insects have sense organs that allow them to see, smell, taste, hear, and touch their environment. ● They use their antenna to feel around and also for their sense of smell Respiration ● Instead of lungs, insects breathe with a network of tiny tubes called tracheae. ● Air enters the tubes through a row of holes along an insect's abdomen, which then diffuses down the blindended tracheae. reproduction Most insects reproduce by sexual reproduction. The female produces eggs, which are fertilized by the male. The eggs are usually placed near the food source and in a place safe from predators. In some insects there is asexual reproduction during which the offspring comes from a single parent.
