Arachnospila trivialis

Arachnospila trivialis

''Arachnospila trivialis'' is a widespread spider wasp of sandy soil areas of the Palaearctic.
Spider wasp - Arachnospila trivialis Quite difficult to identify this species. I have checked all 93 Pompilid species recorded in Greece and came to the conclusion, that this is the best match. Very busy wasp, didn't stay calm even for a fraction of a second. It took me quite a long time and big efforts to make only a few sharp photos.

Appearance

A medium-sized red and black spider wasp. The males have a quite distinctive genital plate, but females are very similar to other species assigned to the subgenus ''Ammosphex'', such as ''A. anceps'' and considerable care is required to identify them.

Distribution

Northern and central Europe, including southern and western areas of Great Britain, and across Asia to the Pacific.

Behavior

''A trivialis'' is single brooded, flying from May to August. The only confirmed prey are spiders of the genus ''Xysticus'' and it may prey on wolf spiders of the family Lycosidae too. Apparently little appears to be known about ''A trivialis'' nesting biology, but like other ''Arachnospila'' species it is likely to excavate a nest in loose sand having already paralysed a spider and concealed it in nearby vegetation. Adults have been observed to visit the flowers of wild parsnip. Interestingly ''A. trivialis'' will prey on spiders of both sexes while most spider wasps prefer to prey on females.
