Butterflies belong to an insect family called lepidoptera. A butterfly starts its life as a tiny egg. When the eggs hatch, a caterpillar emerges. Caterpillars are eating machines. They have massive jaws for munching leaves. In their short lifetime, they may eat as much as 20 times their weight in food!! The caterpillar has a very special body. Parts of the caterpillar’s head.

Now, the pupa (chrysalis) is ready to emerge as an adult. Now, the butterfly has to “blowdry” its wings in the fresh air. Finally, the butterfly is ready to fly!

They are skinny with little knobs on the end. Butterflies use their antenna to smell flowers, plants, and other butterflies. A butterfly has two compound eyes lots of little eyeballs grouped together. Each eyeball sees a little part of what the butterfly is looking at. It's like looking through a bunch of straws bundled together. eye Picture of magnified eye A proboscis is like a long tongue or drinking straw. The butterfly uncoils its proboscis and sips up flower nectar or fruit juice. magnification of proboscis Butterflies have 6 legs (3 pairs). Butterflies taste with their feet! That's how they find flower nectar and the best plants to lay their eggs. The butterfly’s wings are a work of art! The color patterns of butterfly wings are made up of thousands of tiny overlapping scales. Tiny colorful scales cover the both sides of a butterfly's wings. Scales with different colors make patterns and designs on the wings. These patterns are almost the same on the left and right wings, but patterns are very different on the front and back of the wing. Pictures of scales on wings Some butterflies have very colorful wings so other butterflies can see them and find them when they want to mate. Sometimes brightly colored butterflies are poisonous and bad-tasting. When other animals see them, they know not to eat them. Some butterflies have dull colors on their wings. This helps to camouflage or hide them so other animals won't eat them. What have you learned about butterflies??
