👉 Ucidinae are a family of extinct, highly specialized insects that lived during the Cretaceous period, approximately 68-59 million years ago. They were characterized by their large size and sharp, curved bodies, which allowed them to perform complex foraging behaviors. Ucidinae were primarily associated with the Cambrian period, around 54-37 million years ago, when they lived in a variety of environments including forests, deserts, and wetlands.
