About the Agenioideus cinctellus
Agenioideus cinctellus is a spider wasp of the subfamily Pompilinae with a Palearctic distribution. A. cinctellus is a relatively small species of spider wasp being 6–8 mm long. The abdomen is mainly black in colour but the rest of the body is very variable and the legs may vary from whitish to reddish brown, some specimens have spots on the tibia of the hind. There is often an oval spot on the inner edge of the eye.
This species prefers dry habitats and sandy soils. It can be seen searching for prey on vertical surfaces such as old walls. The species has been found on unstable clay under-cliffs on the Dorset coast. In Britain, the flight period is normally June to August but occasionally adults emerge as early as late May.
The main prey species are small jumping spiders of the family Salticidae, but members of the family Thomisidae will occasionally be used. This wasp will also hunt spiders found on vertical or nearly vertical planes, such as cliffs, walls and the overturned root plates of wind thrown trees.
This wasp uses a wide range of natural cavities for nesting, but will also utilise the abandoned burrows of other aculeate hymenoptera... Wikipedia →
