What is the name for the modified forewing structure consistent across the Order Hemiptera?

Answer

Hemelytron

A defining characteristic shared across the vast Order Hemiptera, including the Giant Water Bug family, is the structure of their forewings, which are termed a hemelytron. This structure exhibits a distinct regional modification: the basal portion, closer to the body, is hardened or leathery, providing structural protection, while the distal tip of the wing remains membranous. This pattern of partial hardening is a consistent trait within the order and is present in the Belostomatidae family, contrasting with insects where the entire forewing is uniformly hardened (like beetles).
