Description and notes A medium-sized red and black spider wasp. Identification may be made from Day (1988). The male has a relatively distinct genital plate, but females are very similar to others in the subgenus Ammosphex Wilcke, and considerable care is necessary in identification.
Locally common in suitable habitat in southern England, extending northwards to Yorkshire and Lancashire, also occurring in Wales, mainly on the coast. It is also to be found in the Isles of Scilly and the Channel Islands.
Overseas it is known from northern and central Europe and across Asia to the Pacific coast (Wolf 1972).
