Lepidoptera insects mainly comprise two types of moths and butterflies, about 20 thousands of species are known all over the world, about 8000 more species are known in China, the distribution range is extremely wide, and most of the lepidoptera insects are plant pests. Lepidopteran insects belong to the group of completely metamorphic insects, i.e., a generation undergoes four stages of development, egg, larva, pupa, and adult, where the pupal stage is the metamorphic stage from larva to adult. Most moth insects spin and cocoon, which is a special protection for their safety to pass through the pupal stage. Most butterflies except the butterflies do not form cocoons in the pupation process, but only form naked pupae.

The eclosion adult takes liquid nutrient in a siphon mouth to suck, is provided with the tasks of breeding and spreading offspring, and only grows in a reproductive system in vivo, and the external form does not grow any more. Lepidopteran insects are relatively moist and soft in wings when breaking pupae and coming out, and are also very fragile, and if the lepidopteran insects are damaged by the outside, the flight capability of the adults can be influenced.
