This nest, the size of a football, was constructed within a room that has a permanently open door to the exterior on Dwarsriviershoek farm in Banghoek Valley near Stellenbosch. The nest was secured to the ceiling and hung like a lantern in the corner of the room. A second nest was constructed directly below this one on the floor, among loose crates and wood planks (the above images are of wasps from this second nest).

Distribution

Indigenous to the Palaearctic region. Introduced into South Africa (Western Cape) in 1975 and has the potential to spread through much of the winter rainfall areas of South Africa. Also introduced to other parts of the world including Argentina, Australia, Chile, New Zealand, USA.

Biology

Social, constructing concealed communal paper nests often under the ground. Larvae are fed on chewed-up, soft-bodied insects such as caterpillars. Can be a pest and incidental threat to picnickers as they are protein scavengers, attracted to sugary substances and sting readily if disturbed. Has potential impact on local ecosystems through prey competition; the honey industry as they hunt bees; and on wine and fruit industry through fruit feeding damage and subsequent secondary fungal infection. Control: Destruction of nests.

Many thanks to Derric and Nicholas Wilson for alerting me to the presence of these nests and allowing access to their farm office for photography of the nest and its inhabitants. The nest is now at Iziko South African Museum, where it forms part of an exhibition on this alien invasive wasp.
