Dipogon variegatus is a pompilid spider wasp in the subfamily Pepsinae from the Palearctic.
Identification
Like the other two British species of Dipogon this is an all black wasp with bifasciate wings. The females can be recognised by transverese wrinkles on the first abdominal segment, in males these are less prominent and the subgenital plate at the tip of the abdomen has long ventral hairs.[2]
Distribution
Europe and North Africa.[2] In Britain it is mailnly found in England and Wales with scattered records in the south of Scotland and the central Highlands but has not been recorded recently in Ireland.[3]
Habitat
A wide variety of open habitats including gardens, parks, fields, meadows and coastal heaths.[2]
Biology
This species has been recorded has a flight period from May to October in Britain and it seems to exclusively prey on the crab spider Xysticus cristatus. D.variegatus will utilise almost any kind of pre-existing cavity including dead plant stems, dead wood, masonry cavities and even old snail shells. The nest cavity is plugged with sand grains, soil or plant debris which is bound together by spider silk collected by the female using the maxillar bristles which give the genus Dipogon its name. In small cavities single cells may be constructed but if space permits multiple cells will be built.[2]
