Why do butterflies in Jinhua lay eggs in spring? How do they spend the cold winter?
Details are as follows:

Adult butterflies will migrate, find a place suitable for winter, or find a sheltered place to tighten their wings.

Overwintering in the form of eggs after laying eggs is also the most common.

In the larval stage, you either climb into the soil or curl up in the leaves for the winter.

Habitat characteristics:

Some butterfly larvae often live in seclusion by decorating the leaves of their nests. There are different ways to decorate leaves from one to several, each with its own style or skill.

Banana butterfly larvae can stick the edge folds of banana leaves to the nest for seclusion, while rice butterflies often connect several leaves together to build nests inside. Larvae with nesting habit or web-building habit never go far when they feed near their habitat. When disturbed, they will immediately retreat into the nest to hide, which is completely different from the habitat habit of ordinary butterflies.
