This wasp has been on my hit list to find so was very pleased to see several today.

Anoplius viaticus, commonly known as the black-banded spider wasp, is a species of spider wasp. These wasps are known as spider wasps because the females capture spiders to provide their offspring with food

Episyron rufipes spider hunting wasp (Cavenham heath NR suffolk)

Prey collected
Episyron rufipes is a specialist hunter of orb-web spiders. Araneidae (Araneus) and Metidae (Meta) are the usual prey, with a few records for Lycosidae.

Distribution
Episyron rufipes is widespread in lowland Britain on any sandy soils. Away from the south-east heaths and coastal systems, inland records are scattered north to Humberside. In Wales, north west England and in Ireland, E. rufipes is mostly confined to the coast.

Spider hunting wasp (Auplopus carbonarius )?

This isn’t a new sighting and the wasp has been posted before on my blog but this is one at work .

I saw this wasp on my front path wrestling with this spider. which it paralysed then dragged it off. It will drag it to a burrow where it will lay an egg on it which will then hatch and devour the spider.

I wont complain because I hate spiders.

The spider is a Mouse Spider I believe.

Auplopus carbonarius (Pompilid) *spider-hunting wasp*

A generally scarce species although perhaps especially prone to under-recording through its secretive and elusive nature.  Food/ prey these are most frequently spiders in the family Clubionidae, but there are other records for gnaphosids, salticids, agelenids, thomisids, lycosids, segestriids and anyphaenids.The nesting behaviour (which is summarised by Richards and Hamm (1939) and Day (1988)) is rather more complex than that of most pompilids and demonstrates tremendous versatility on the part of the female. The nests are built in cavities in a great variety of situations, non-British reports citing nests beneath stones, in stone walls, in tree stumps (often in old beetle burrows), under bark and in crevices of tree trunks, in empty galls of cynipid wasps, in empty burrows of earthworms or cicadas, in old snail shells, in beehives, in an old cloth in a garden, behind a door frame, in a loft and in an old mirror in a garden. The nests may sometimes be mixed with those of other aculeates such as Anthophora bees andAncistrocerus wasps and, indeed, A. carbonarius may use old nest holes of these species. Females construct small, barrel-shaped cells which are laid on their side. These are manufactured from small pellets of clay obtained from damp areas, such as river banks or beneath stones, and carried to the nest site between the mandibles and a group of specialised hairs on the basal mouthparts. Water is also collected separately, probably to aid nest building. Completed nests may consist of ten or more cells (as many as 34 on one occasion) arranged in a block. These nest cells, constructed prior to prey capture, are stocked with a wide variety of spiders obtained from amongst vegetation. One prey item is placed in each cell. The wasp may fly with small prey individuals (unusual in the Pompilidae where the prey is usually dragged along the ground)….. BWARS
