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.
