Unknown facts about butterflies

Butterflies are very interesting insects! They live in all parts of the world and there are thousands of kinds. Some are less than a half-inch long, while others have a wing span of eight to 10 inches!
The wings of butterflies come in many colors and patterns. Some wings are solid bright colors, like blue, yellow, orange or red. Many butterflies have intricate patterns on their wings. The designs are pretty, but their purpose is to fool birds! They may have spots on their wings that look like animal eyes. That helps to scare away birds so they don’t eat the butterflies! Others have wing patterns that look like leaves, so they blend in with bushes and trees, and the birds can’t see them.
Butterflies fly very well, and can change directions easily. They can land quickly. Their wings are made of many little scales.
During the day, butterflies fly around looking for food to eat. They use their “proboscis” to suck the nectar from flowers. It is a long tube that looks like a tongue. When they aren’t eating, they roll up their proboscis. They also will eat tree sap and decaying fruits and animals.
Butterflies find their way with the use of their antennae, which have tiny knobs on the ends. They feel things with the knobs.
Some butterflies live for more than a year and others live for just a few weeks. Most live their entire life in one small area, but there are several kinds that migrate. In winter, they fly south to warmer weather. They may fly hundreds or even thousands of miles. When spring comes, they fly back to their home!
Some kinds that migrate are the well-known milkweed or monarch butterfly, the painted lady butterfly and the common cabbage butterfly.
