The butterfly is a generic name for a group of insects in the insect, amphiesmenoptera and lepidoptera, and nearly 20,000 species have been recorded worldwide.

Butterflies are diurnal insects and their activities are all during the daytime, with flight posture and speed varying from species to species. Adult butterflies suck nectar and juice by siphoning mouth parts, and also suck clear water from streams or mosses, bird and animal fecal fluids, and animal carcasses' body fluids, with different feeding habits for different species.

Due to the different habits of adult butterflies, the structure of the external genitalia changes to ensure that different species do not interbreed. Before mating, most butterflies go through a period of courtship flight, and some species have to have a large space for their nuptial flight.

Butterflies are important ecological indicator species because of their sensitivity to ecological changes.

The larvae and adults of butterflies, which have different lifestyles, feed on different objects. Many of the adult stages are nectar suckers. They act as pollen dispersers to many plants in nature during nectar collection.
