In what season do butterflies usually appear?

Butterflies usually appear from late April to mid-May in spring.

Butterflies are commonly known as "butterflies". There are about 65,438+04,000 species in the world, most of which are distributed in America, especially in the Amazon River basin, and all over the world except the cold regions of the North and South poles. In Asia, Taiwan Province Province is also famous for its wide variety of butterflies. Butterflies are usually brightly colored, with various spots on their wings and bodies, and a pair of rod-shaped or hammer-shaped antennae on their heads (this is the main difference from moths, which have diverse antennae). The largest butterfly can spread its wings up to 24 cm, and the smallest is only 1.6 cm. Big butterflies attract people's attention, and some people collect all kinds of butterfly specimens. In the United States, "butterfly watching" migration, like "bird watching", has become a new activity, attracting many people to participate. There are many kinds of butterflies that are the main pests of agriculture and fruit trees.

So generally speaking, its life span is relatively short. Generally speaking, its life is related to temperature. The higher the temperature, the faster its metabolism and decline. The temperature is slightly lower in spring and late autumn, but the life span will be longer. Its activity is directly controlled by the outside temperature, so butterflies usually break their cocoons in spring.
