Thrincopyge
jewel beetles
Thrincopyge is a genus of jewel beetles (family Buprestidae) in the subfamily Polycestinae. The genus contains three described species: T. alacris, T. ambiens, and T. marginata. Adults are known for their striking metallic coloration, typically combining blue or green with vivid yellow. Larvae develop within the dried flowering stalks of sotol plants (Dasylirion spp.), while adults conceal themselves at the base of the plants among the long, strap-like leaves. The genus occurs in the southwestern United States and northern Mexico.
