Description

Bembecinus tridens can reach a length of 7–11 millimetres (0.28–0.43 in). The body is black and yellow.

Biology

These wasps fly in one generation from early June to late August. The females dig a unicellular nest, though a single female digs 1-8 nests in succession. After an egg is laid in the cell the prey item (various families of Homoptera) is introduced.[2][3] The species is parasitized by Hedychrum chalybaeum.[4]

Distribution and habitat

This species can be found from Western Europe and North Africa to Japan and China.[5] They are common inhabitants of sandy areas.
