Benefits of Ladybugs

Ladybugs, also known as ladybirds or coccinellids,
are small beetles approximately 1/4-inch in length
with dark orange hard shells covered in black
dots. These beetles can show up in large numbers
in some areas and will occasionally attempt to
move indoors to cause a nuisance in the home,
but overall these are bugs you want to have
around because of their benefits.
Ladybugs eat aphids; one ladybug can eat up to
400 a day, several ladybugs can eat thousands.
Ladybugs are a huge benefit to a garden
Reduce Insect
Population
Ladybugs are predatory beetles that eat a
large number of aphids (plant lice) and other
harmful bugs. Even in the larval stage,
ladybugs will normally consume hundreds of
aphids and will grow into adults that may eat
up to 5,000 aphids in a lifetime. This greatly
reduces the population of harmful insects
that will otherwise destroy your plants.
Ladybug Anatomy

There are eight parts to the ladybug anatomy, each with its own
purpose. A ladybug is an insect, a beetle actually, and it has most
of the same anatomical parts as every other insect, as well as a
few parts that are distinctive to the ladybug. All ladybugs are less
than ¼ inch long, oval or round shaped, and have six short legs.
Ladybugs usually have very bright colors, like red or orange, and
often have some sort of pattern on them, like spots. These colors
and patterns are thought to warn predators of the ladybug’s bad
taste and poison. Sometimes, though, the ladybug will be a solid
color with no pattern at all, and can be yellow, brown, or black.
The eight body parts are the head, antenna, eyes, pronotum,
thorax, elytra, wings, and legs.
Ladybug lifespan

After a female lays her eggs, they will hatch in
between three and ten days, depending on
ambient temperature. The larva will live and
grow for about a month before it enters the
pupal stage, which lasts about 15 days.
A ladybug can live from one to two years, but
the life cycle, from egg to adult, is about a
month. Lady's bugs live atlest through summer
they go away in winter It also depends on if it
gets eaten or squashed.
Life cycle
 Eggs
are tiny, spindle‐shaped, and
arranged in clusters.
 Larvae are usually elongated, “alligator”
shaped, slightly pointed at the rear, and
their body is covered in tiny bristles.
 Pupae are slightly round and dark
colored. You can find them attached to a
surface by their hind ends.
 Adults are sphere‐shaped, smooth, and
have easily recognizable colors and
markings.
