Pepsis thisbe
Thisbe's tarantula-hawk wasp
Pepsis thisbe is a large spider wasp in the family Pompilidae, commonly known as Thisbe's tarantula-hawk wasp. Females are 32–44 mm in length with a dark blue body and orange wings. The species exhibits pronounced sexual dimorphism: females have curly antennae and a 7 mm stinger, while males have straight antennae and lack stingers entirely. Adults are nectarivorous, feeding primarily on flowers, but females hunt tarantulas as food for their larvae. The species is distributed throughout the American Southwest in desert areas.
