Research Significance of Wing and Vein among Insecta

Insects are the only flying animals among invertebrates, but also the earliest animals with wings in animal
kingdom. The presence of wings not only expands the insects’ activity and distribution scope, but also enhances
their speed, which brings superiority and competence in variety of aspects such as foraging, calling, finding
places for spawning, winters and summers, avoiding predators and so on. Wing is an important condition for
insecta to become the most prosperous biological community. Among various insects, wings experienced a wide
range of variation, so the characteristics of wings have become an important basis for the study of insect
classification and evolution.
