Extended data:
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 habits or web-building habits feed near their habitats and never go far. When they are disturbed, they will immediately retreat to their nests and hide.
Water is an important part of organism's metabolism. Therefore, we can often see butterflies stopping on the wet ground to absorb water, especially the slightly salty water, which can attract them to drink.
