Ladybug Anatomy
There are eight parts to the lady bug 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 � 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.
Head
The ladybug�s head is round and thin and includes the ladybug�s mouth, eyes, and antennae.
Antenna
The antenna is what helps a ladybug smell, taste, and feel its way around. Ladybugs don’t see as well as they can smell and this is how they find the tiny bugs that they eat.
Eyes
A ladybug has two eyes but it doesn�t see very well. Ladybugs can only see the difference between dark and light, as if everything was a black and white photo, but they cannot see colors at all.
Pronotum
The pronotum is the part right behind the ladybug�s flat head that sort of makes the head look round. The pronotum actually protects the ladybug�s head and helps to hide it. Sometimes the pronotum will have spots on it, too.
Thorax and Abdomen
The thorax and the abdomen, is the body section that the legs and wings are attached to, and the part that holds the ladybugs digestive system, the reproductive organs, and the stinky, poisonous gel.
Elytra
Ladybugs have a shell, or hard case, that protects their wings and also protects them from predators. The Elytra is also the part that shows the ladybug�s colors and patterns to predators to warn them off. The Elytra is exactly the same on the right side as it is on the left, they are a mirror image, or symmetrical, to one another.
Wings
The wings are what helps the ladybug fly. Ladybugs don�t seem to have a very good sense of direction when they fly around, though. They seem almost clumsy. Perhaps this is because of the wings being stuck underneath the Elytra all the time. Every time the wings are used, they have to carefully fold them back up to hide underneath the Elytra.
Legs
The six short little legs of a ladybug help it to walk, but they do more than that. The feet of a ladybug helps it smell, and when a predator captures a ladybug, the bad tasting and poisonous gel will ooze out of the legs, sometimes saving the ladybug�s life. Wouldn�t you spit that out?
Ladybug
Ladybugs are colorful for a reason. Their markings tell predators: “Eat something else! I taste terrible.” When threatened, the bugs will secrete an oily, foul-tasting fluid from joints in their legs. They may also play dead. Birds are ladybugs’ main predators, but they also fall victim to frogs, wasps, spiders, and dragonflies. Ladybugs lay their eggs in clusters or rows on the underside of a leaf, usually where aphids have gathered. Larvae, which vary in shape and color based on species, emerge in a few days. Seven-spotted ladybug larvae are long, black, and spiky-looking with orange or yellow spots. Some say they look like tiny alligators. Larvae grow quickly and shed their skin several times. When they reach full size, they attach to a leaf by their tail, and a pupa is formed. Within a week or two, the pupa becomes an adult ladybug.
history
Ladybugs are happy in many different habitats, including grasslands, forests, cities, suburbs, and along rivers. Seven-spotted ladybugs are native to Europe but were brought to North America in the mid-1900s to control aphid populations. Ladybugs are most active from spring until fall. When the weather turns cold, they look for a warm, secluded place to hibernate, such as in rotting logs, under rocks, or even inside houses. These hibernating colonies can contain thousands of ladybugs.
The name “ladybug” was coined by European farmers who prayed to the Virgin Mary when pests began eating their crops. After ladybugs came and wiped out the invading insects, the farmers named them “beetle of Our Lady.” This eventually was shortened to “lady beetle” and “ladybug.” NASA even sent a few ladybugs into space with aphids to see how aphids would escape in zero gravity.
10 Things You Didn’t Know About Ladybugs
Learn why you want this charming insect in your backyard.
- They can have as many as 16 spots, but some ladybugs have no spots at all.
- While most ladybugs are good, there is one nonnative species that people don’t like. The Asian lady beetle was introduced in California in 1916. Today it’s more common in the East.
- A ladybug can eat up to 50 aphids a day.
- One of the most common ladybugs is the seven-spotted lady beetle. It has seven black spots on its back.
- Females will lay up to 1,000 eggs within a few months, generally from spring to early summer.
- You might hear ladybugs go by a few different names, including: Ladybirds, Ladybugs, Lady beetles and Lady cows.
- Ladybugs usually protect themselves from predators in one of two ways: They either play dead or secrete a fluid from their legs to make themselves taste bad.
- One common belief about ladybugs is that you can tell their age by their number of spots, but this is a myth.
- You can find out about 6,000 different species of ladybugs around the world. There are about 500 species in the United States alone.
- Ladybugs are great garden predators. Here are six “bad bugs” they’ll eat:
Is there a difference between lady beetles and ladybugs?
Although these insects are commonly called “ladybugs,” they are members of the beetle order,
Coleoptera. The Coleoptera are unique from other orders in that they undergo complete
metamorphosis (that is, have larva and pupa stages in their life cycle), and their forewings have
modified into a hardened cover (elytra) that protects the insect. “True” bugs belong to the
order Hemiptera, and include boxelder bugs, plant bugs, and squash bugs.
Immature True Bug
Though taxonomically incorrect, lady beetles are still commonly
referred to as ladybugs. Other frequently used common names are
ladybirds or ladybird beetles.
What do ladybugs eat?
Both adult and larval ladybugs are known primarily as predators of aphids but they also prey on
many other soft‐bodied insects and insect eggs. Many of these are agricultural pest such as
scale insects, mealybugs, spider mites and eggs of the Colorado Potato Beetle and European
Corn Borer. A few ladybugs feed on plant and pollen mildews and many ladybugs supplement
their meat diet with pollen.
What eats ladybugs?
Ladybugs are not commonly eaten by birds or other vertebrates, who avoid them because they
exude a distasteful fluid and commonly play dead to avoid being preyed upon. However,
several insects, such as assassin bugs and stink bugs, as well as spiders and toads may
commonly kill lady beetles.
How many different species are there in the US? In the world?
There have been over 500 species of ladybugs identified in the United States, and over 4500 in
the entire world.
How long do they live?
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. After the pupal stage, the adult ladybug will live up to one
year.
Why are they so brightly colored?
Ladybugs bright colors serve as a warning – they indicate any potential predators of the
distasteful repellents the beetle will release if attacked. Ladybug spots are part of the bright
warning pattern discussed in the previous question.
What’s with them in my house during winter?
During the winter months, ladybugs seek out a warm place to hibernate. Many seek out cracks
around buildings, including people’s homes. They mass together to stay warm throughout the
winter. Don’t worry, they will not harm you or any part of your home, and they will be gone by
spring.
How did non‐native species get here?
Non‐native ladybug species may have been introduced to the United States by scientists as an
attempt to control crop‐damaging aphids, or they could have hitched a ride with any vegetation
that was brought over from Europe, Africa, or Asia.
