This forum is a place to discuss matters related to BWARS and general matters related to aculeates.
It is not intended as a forum for identification queries. We may add this feature in due course, but meanwhile, if you need help identifying bees, wasps and ants, please use either iSpot or the BWARS forum on Yahoo.
During my identification and learning process (never ends!) I took photos of the bits of wasp specimens which were alluded to in the key(s), mostly first and last below, to help me understand what was meant:
Yeo P.F. & Corbett S.A. 1983 Solitary Wasps. Naturalist's Handbooks 3 CUP
Richards O.W. 1980 Scolioidea, Vespoidea and Sphecoidea RES.
and worth every penny for the clear illustrations and descriptions:
Lomholdt O. 1984 The Sphecidae (Hymenoptera) of Fennoscandia and Denmark. Brill (publisher, not a comment on how good I think it is!)
