Greek astatos 'restless'.
14 spp. in our area(1), 80 spp. worldwide(2)

Compact sphecids, with large eyes. Males have "wrap-around" (holoptic) eyes. Two widespread eastern species: A. unicolor is all black, A. bicolor has red abdomen, though there may be sexual differences in coloration as well.
Astata can be distinguished from the other nearctic Astatinae genera by having the posterior edge of the 2nd submarginal cell as long or longer than that of 1st submarginal cell (in Dryudella and Diploplectron the 2nd submarginal is shorter than the 1st)(3)
Pentatomidae nymphs(4)
