Description

Arachnospila consobrina is a little-known Palaearctic spider wasp. Like other members of the sub-genus Ammosphex this is a medium-sized red and black spider wasp. The males have a quite distinctive genital plate, but females are very similar to related species such as A. anceps and A.trivialis but can be identified by their relatively hairier head. Northern and central Europe, marginally in southern Britain, and also Africa and Asia. A consobrina is single brooded, flying in July and August. The only observation of A. consobrina with prey concerns a female found under a stone near Constantinople carrying a Segestria florentina which was reported in Fahringer.The nesting biology of A. consobrina is almost completely unknown, but like other Arachnospila species in the sub-genus Ammosphex it is adapted to digging in loose sandy soils. Arachnospila is a predominantly Holarctic genus of spider wasps, with limited representation in montane habitats in Neotropical and Afrotropical regions. They are found in open habitats and at forest edge, the nests may contain more than one cell.
