Prionyx atratus

Prionyx atratus (Lepeletier) 1845. This species occurs transcontinentally from southern Canada to northern Mexico (Krombein 1979). It is quite widespread across the LP, but rare in the UP.

BIOLOGY: Wasps nest in gravelly or sandy (heavy) soils, constructing one-celled nests after procuring prey. A single adult grasshopper is used to provision the cell, with over 20 species of acridids recorded as prey (Krombein 1979).

COLLECTION DATES: 117 specimens, 10 July to 3 October, with the majority of specimens taken in August. This coincides with the appearance of most adult acridids.
