BWARS forum - first, please read this

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.

Key to Wasps of the family Vespidae - corrected version

This is a corrected version of the key to Vespidae wasps, issued in the BWARS Newsletter (Spring 2019 issue).

Gasteruption jaculator film and question

I have some impressive footage of a Gasteruption jaculator ovipositing inside a common yellow face bee cell inside my observation nest box and the filming of the larvae eating bee larvae/forage and cannibalism with its Gj neighbour! Has anyone any proof positive, papers, similar that this species actually uses O. bicornis as a host? I cannot find any other than one found that is German in German. The film will be on my web site as I await more developments.
