Ladybugs Under a Microscope

When scientists study animals like ladybugs, they often look at the way they move and behave. Scientists also take notes and draw pictures of what they see. This is called gathering data or collecting clues.

A ladybug’s bright colors help to protect it from predators. The color tells the predator that the animal isn’t good to eat. The ladybug might also release a smell from special glands in its legs that make it taste bad to the predator. Ladybugs can also ‘play dead’ by sitting very still and looking like they aren’t moving. This is a good way to protect themselves from birds that might try to eat them.

Adult ladybugs have wings that they can fold up and down when they are not flying. The wings have a hard outer shell, called an elytra, that covers the soft, flexible hindwings used for flight.

The elytra can be used to help the ladybug hold onto surfaces, like leaves or bark, when it is climbing or crawling. The elytra also has lots of tiny bumps and spikes that are designed to grab or pierce the skin of any predator that happens by.

When a ladybug is ready to mate, it releases a special pheromone that lets other ladybugs know it is looking for a mate. When a ladybug finds its mate, the male and female will copulate (stay together) for about 2 hours. The female will then lay her eggs.

The female will usually place her eggs on the outside of the elytra, but she might also hide them in crevices or between the scales of another insect. The eggs will hatch into larvae, which resemble the adult ladybugs. The larvae will feed on the leaves and flowers of plants. They will grow larger and change to a darker color as they mature. Then, the female will release a chemical that causes the worm-like larvae to transform into adult ladybugs.

As the larvae grow, they will shed their old skin three times before they pupate. You might notice some crumpled black things on the floor or in your cup. These are the shed elytra of the previous ladybugs that were in the cup with you!

Scientists are still learning about the behavior and life of the ladybug. They hope to use these discoveries to help people find more ways to protect the ladybug and other insects that are important for our planet. Ladybugs are very important to the environment, because they eat a lot of pests that can damage crops and other plants. This makes the ladybug a very useful insect for farmers and gardeners. We even have a special breed of ladybug that is designed to eat aphids. That helps to keep the aphid population down and saves our crops!
