Butterfly is a completely abnormal insect, that is to say, it will go through four stages in its life: egg, larva, pupa and adult. There are about 14000 species in the world, most of which are distributed in America, especially in the Amazon river basin. There are 1200 species in China.
Butterflies are usually brightly colored, striped and colorful. They have all kinds of spots on their wings and bodies. The largest butterfly can spread its wings about 28 ~ 30 cm, and the smallest is only about 0.7 cm. The main difference between a butterfly and a moth is that the butterfly has a pair of rod-shaped or hammer-shaped antennae on its head, and the moth has various antennae.

Characteristics of butterflies
1. The scales on the front of most butterflies' wings are brightly colored, and the wings are not fluffy. A few butterflies in Nymphalidae have obvious hairs on the roots of their hind wings.
2. Most butterflies have rod-shaped antennae with enlarged tips.
3. The butterfly has four wings folded and stands upright on its back to rest.
4. The hair on the butterfly trunk is sparse (compared with moths).
5. The root of the rear wing visible on the belly of the butterfly is curved (attached) and has no wings. It helps to improve the flying speed, because butterflies generally fly faster than moths in daytime activities.
