Hi: Can you help me out in identifying this bug? Thank you.
This is an immature Giant Mesquite Bug. Adults have fully developed wings and can fly. If you are writing from Arizona, it is Thasus acutangulus. We also get images of this genus from Mexico, but the markings are a bit different. We are not sure if the Mexican population represents a local color variation, a subspecies, or a different species in the same genus.
