A preliminary survey of the aculeate wasps and the bees of the lower reaches of the Nossob River Valley, Kalahari Gemsbok National Park, South Africa

Abstract

An annotated list of aculeate wasps and of bees collected during a preliminary survey of these insects in the lower reaches of the Nossob River Valley, Kalahari Gemsbok National Park is presented. Flowers visisted, and notes on provision and nest type are given. Meloid beetles collected on the flowers are listed. The species composition and geographical affinities of the community of aculeate wasps and of bees in relation to those of four sites in the Karoo Biome (in Namaqualand, in the southern Great Karoo, in the Little Karoo and in the easternmost extension of the Nama Karoo) are discussed briefly.
