Pepsis mildei, also known as Milde's tarantula-hawk wasp, is a species of predatory spider wasp native to the Western Hemisphere. These wasps capture live tarantulas to feed to their larva; the adults graze on flowers.[1] Tarantula hawks generally have no meaningful predators.[2] The wing color is black and/or orange, with rare leucistic wing coloration known in males.[3][4] The wings of P. mildei are duller overall than those of Pepsis grossa or Pepsis cinnabarina.[5] Per Edward Essig, Milde's tarantula-hawk wasp usually measures 20–30 millimeters in length and is a metallic blue-black overall, with "the antennae reddish, dusky at extreme base in the male and the basal third dusky in the female; the wings fiery red with the bases and apices dusky".[5] In all tarantula wasps, the antennae can be used to distinguish between males and female: males are straight or gently arced, while the females have curved antennae.[6] The lifespan of males is one to two months, while female Milde's tarantula-hawk wasps live for a longer span of time.[1]
