The feeding objects of butterfly larvae are different according to different insect species, and larvae prefer to eat leaves; Some species, such as butterflies with orange spots, are addicted to flower buds.
Larvae that feed on plant leaves, such as the first instar, often eat mesophyll on the back of leaves and leave the upper epidermis to form transparent spots similar to glass windows. Later, larvae feed on leaves, or nibble inward from the edge of leaves; As the bug grows up, it eats more and more.

Habitat characteristics
Butterfly larvae often have the habit of seclusion and decorate their nests with leaves. The methods of decorating leaves vary from species to species, and the styles or techniques are also different. 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.
