lly bigger and more brightly colored than those in cooler countries, and there are more different kinds. Usually the male butterfly is more brightly colored than the female. The females have bigger and heavier bodies, since they carry the eggs. The gay colors of the male help to attract the female and the duller colors of the female make them less likely to be caught by enemies before they have laid their eggs.

Some butterflies have a bright pattern of colors on the upper surface of their wings which show when they fly, but when they rest on a tree or leaf they close their wings. On the undersides of their wings there are green and brown markings which look like the tree or leaves. They are then difficult to see. The best example of this is the Dead Leaf Butterfly. When its wings are closed, it looks like the holes in a dead leaf. When a bird is chasing a butterfly, and it closes its wings, it seems to have disappeared completely.

Many butterflies have round marks on their wings that look like eyes. When they are resting, and their wings are folded, these cannot be seen. when a bird sees one, and begins to attack it, the butterfly opens its wings. The bird thinks that it sees two eyes staring at it, and frightened, it flies away.
