A butterfly is an insect. Like all insects, it has three main body parts: head, thorax, and abdomen. It also has special butterfly adaptations.

Tiny, overlapping scales on its wings give it color. Veins in the wings give them strength.

The butterfly, like all insects, has six legs. Sensitive cells on its feet “taste” the plants on which it lands.

A butterfly has big eyes and sharp vision to help it find flowers and a mate. It can see ultraviolet light and shades of color that we cannot!

Some butterflies have long tails on their hind wings. These tails often have spots that look like eyes. Together, the eyespots and tails may look look like a head with antennae to a hungry bird. They fool the bird into pecking at the back end of the butterfly’s wing instead of its head—giving the butterfly a chance to escape!

• Butterflies have big eyes and sharp vision.

• Butterflies have 3 main parts.

• Butterflies have sensitive cells on their feet.

• Butterflies have long tails with spots.
