Life habits of butterflies:

Butterfly is a completely abnormal insect, which needs to go through four stages of development: egg, larva, pupa and adult. The first three stages of development (i.e., eggs, larvae and pupae) are usually called infancy. The development process of butterfly eggs from leaving the mother to adult sexual maturity is called life history or life history, and usually this process is called first generation.

There is a generation of species every year, that is, a species, which is characterized by the fact that the population is less affected by small changes in the environmental climate, but the impact caused by large changes in the environmental climate will be more significant; There are more than one generation of species, that is, multiple generations. Generally, with the increase of average temperature, the number of generations per year increases. On the premise that the host is guaranteed, the population has strong diffusion ability, and the population number is greatly affected by environmental and climate changes.

Butterflies are diurnal insects, their activities are all in the daytime, and their flying posture and speed vary from species to species. Adult butterflies suck nectar, fruit juice, tree juice, syrup or fermented products, as well as clear water, animal droppings and animal body fluids on streams or mosses with siphons. Different species have different feeding habits.
