Are ladybugs really ladies? Are all ladybugs red? What happens to them in the winter? Exciting science projects and fun stuff to do in this issue will help you discover the answers to all your questions about ladybugs!
A Ladybug Investigation
The best way to learn about something is to watch it. Scientists do a lot of watching, or observing, to learn about things, especially insects like ladybugs. In this project, you will get to look for ladybugs and then watch them to learn about them, just like a real scientist! Make sure you get permission from an adult before you start this project.
What You Will Need:
What To Do:
If you want to keep your ladybugs for a couple days to watch them some more, you will need to give them something to eat. Soak two raisins in water for 15 minutes. Cut the raisins in half, then put them in the bottom of the ladybug jar. Even though your ladybugs have food and water now, they will still be happier in their natural home. After observing them for 2 or 3 days, make sure you let them go in the place where you found them so they can get back to their normal life of hunting aphids and laying eggs to make more ladybugs!
Here are several fun ladybug activities you can do this summer!
Activity 1: Find Ladybug Larvae
A ladybug larva is a baby ladybug. Ladybugs go through different stages, and for most of their lives they don't even look like the pretty red and black ones we are used to seeing! Your parent or teacher can tell you more about the different stages of a ladybug's life cycle. Try to find ladybug larvae (that means more than one, larva means one) by looking in the same types of places as you did in the Ladybug Investigation project. A great place to find ladybug larvae is on a rose bush. Aphids love to eat rose plants and since ladybugs love to eat aphids, many ladybugs will lay their eggs on the leaves of rose bushes so that when the larvae hatch out of the eggs, they will have plenty of food waiting for them! If you can find some larvae and some aphids, you can collect them in a container and watch the ladybug larvae change into adult ladybugs! Just be sure to provide them with plenty of aphids and other small insects to eat. They will also need air holes and water. Put a wet cotton ball or paper towel in the bottom of the container to give them water. Note: Instead of using a jar, a Pop-Up Insect Habitat also makes a great home for your insects!
Activity 2: Make Ladybug Prints
You'll need a potato (cut in half), paint in ladybug colors (red, orange, or yellow), a paper plate, art paper, a black marker, and a black ink pad. Put some of the paint on the paper plate and dip the round, cut end of one half of the potato into the paint, then press it firmly onto your paper like a stamp to make a ladybug's body. Stamp as many ladybugs onto your paper as you want. Once the paint dries, you can finish your picture by using your thumbprint in the black ink to make a head and your pinky finger to make spots. Use the marker to give your ladybugs wings, legs, and antennae. You might want to use other paints or markers to draw leaves, aphids, and larvae on your picture also.
Activity 3: Act Like A Ladybug
Make antennae like a ladybug's by attaching two black pipe-cleaners to a headband (or you can make a headband by attaching pieces of string to a strip of cardboard and tying the string behind your head). Stick a small Styrofoam ball onto the end of each pipe-cleaner. Paint the balls and the headband black. Once it is dry, put the antennae on and imagine what it would be like to only be able to feel and smell through your feet and those antennae, the way a ladybug does! Can you think of anything else you could do like a ladybug?
Activity 4: How Much Do You Know?
Write your own science book about ladybugs! Include everything you know about them. One way to do it is to make one page for each thing you know about ladybugs, and then either draw pictures for each page, or find pictures that you can cut out of magazines or print from the internet. Make sure you get permission before cutting anything up or searching on the internet! Another idea is to ask an adult to help you take pictures of real ladybugs that you find. When you have all the pages ready, make a nice cover for your book, and punch holes in the same places in all of the pages, then use string to tie them together, or put them in a three-ring binder. You can use this book to share what you have learned about ladybugs with your siblings and friends.
Ladybugs are sometimes called ladybirds or ladybird beetles.
Ladybugs flap their wings about 85 times in one second when they fly!
Ladybugs have big appetites - by the end of its life, a ladybug will usually have eaten as many as 5,000 aphids!
A ladybug's spots fade as it gets older.
What do you called a nervous beetle? (Answer: A jitter-bug!)
Why did the beetle get kicked out of the park? (Answer: Because he was a litter-bug!)
What do bugs have that no other animals have? (Answer: Baby buggies.)

What Is A Ladybug?
Ladybugs are insects. They are part of a group of insects called beetles. Even though they are called ladybugs, not all of them are females! In order to make baby ladybugs, there has to be a female and a male ladybug. All insects, including ladybugs, have three main body parts: a head, thorax, and abdomen. They have six legs, two antennae, and special compound eyes so they can see in many directions at once. Many insects have wings. For more details about insect anatomy, classification, and habitats, visit our Insect Investigations page. Talk about the body parts of a ladybug. If your kids caught ladybugs in the "Ladybug Investigation" project, let them locate each body part on a ladybug as you talk about it.
Ladybug Life Cycle
Just like all beetles, ladybugs go through different stages of life. Young ladybugs actually don't look anything like the pretty red and black adult ladybugs we are all used to seeing. If you saw one that wasn't an adult yet, you might not even recognize it. The stages that ladybugs go through are all steps in a very complex process called metamorphosis. (Other beetles, butterflies, and amphibians like frogs go through metamorphosis too!)
Stage 1: Egg
A female ladybug lays a cluster of tiny yellow eggs. Ladybugs usually lay eggs on leaves where there will be plenty of food for the babies when they hatch. After about one week, the eggs will hatch and small odd-looking creatures appear! (Here is a picture of some ladybug eggs on the back of a leaf.)
Stage 2: Larva
The odd-looking creatures that hatch out of the eggs are called larva (larvae if there are more than one). They have long bodies with six legs. They are mostly black with colored spots and they look sort of like little alligators. The ladybug will live as a larva for about two to four weeks of its life. During that time, the larva will shed its skin several times. Each time, the skin underneath allows it to grow a little bit bigger. While it is a larva, the ladybug will eat a lot; it can eat as many as 400 aphids! When the larva has grown as much as it needs to, it attaches itself to a leaf to get ready for its next stage of life. (Here is a picture of a ladybug larva.)
Stage 3: Pupa
The larva attached to the leaf is now a pupa. It will stay attached to that leaf while it changes into an adult. The pupa does not eat or move because it stored up plenty of food in its body while it was a larva. After about five days, the pupa has changed in incredible ways and is ready to "hatch" again as an adult ladybug! (This is a ladybug in the pupa stage.)
Stage 4: Adult
Now the ladybug emerges from its pupa as a pretty adult ladybug! These are the kind of ladybugs we are used to seeing. It now has two sets of wings. One set of wings is the hard brightly-colored part that helps us recognize ladybugs. This hard set of wings is called the elytra (say: EL-LIE-TRA) and it protects the fragile flying wings underneath. The ladybug has an oval-shaped body, six legs, two antennae, a head with two eyes, a thorax that is called a pronotum, and an abdomen (the part of the body that is covered by the elytra). When the pupa hatches as a new adult ladybug, it doesn't have any spots yet and its elytra are wet, soft, and pale colored. They will dry out during the ladybug's first day as an adult and it will soon be a pretty bright color with black spots! Ladybugs can actually be red, orange, or yellow! Some kinds can even be gray, brown, or all black, but they are less common, and it's hard to tell they are really ladybugs since their spots are harder to see. Scientists have counted over 5,000 different kinds of ladybugs in the world! Each of these different kinds has special characteristics, such as color, number of spots, and the shape and size of it's body. Check out these pictures of different kinds of ladybugs in colors other than red!
As an adult, the new ladybug can eat up to 75 aphids a day. Towards the end of the summer, ladybugs like to eat pollen and some types of plants so that they can store up fat for the winter. During the winter, ladybugs hibernate. To stay warm, they usually huddle together in groups and bury themselves under piles of leaves, grasses, or rocks for protection from winter weather. When spring arrives, the ladybugs will begin to wake up and come out looking for a tasty meal of aphids! They will begin to lay eggs that will grow into more ladybugs.
To allow kids to see ladybugs change from larva to pupa to adult, we highly recommend the Ladybug Land kit! Also see Activity 1 in "Ladybug Fun" for tips on finding and raising your own larvae.
