Quick Summary

The pronotum is the dorsal plate of an insect's prothorax. It is a significant part of the thorax, located between the head and the wings. This prominent structure is essentially the expanded top of the prothorax. In some insects, like heteropterans, a triangular or U-shaped scutellum projects from beneath the hind margin of the pronotum.12
