Butterflies are common all over the world but the ones in hot countries are usually bigger and more brightly colored than those in cooler countries, and there are more different kinds. Usually the male (雄性) butterfly is more brightly colored than the female (雌性).The females have bigger and heavier bodies because they carry the eggs. The gay (艳丽的) colors of the male help to attract the female and the dark colors of the female make them difficult to be caught by enemies before they have laid their eggs.      Some butterflies have bright colors on their wings (翅膀) which show when they fly, but when they stop on a tree or leaf, they close their wings. On their wings there are green and brown marks which look like the tree or leaves. They are difficult to see. The best example of this is the Dead Leaf Butterfly. When its wings are closed, it really looks like a dead leaf. There are even marks that look like the holes in a dead leaf. When a bird is running after 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 can't 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 (凝视) at it, and, frightened, it flies away.
