These were flying in Yorkshire for a week or two around June 20. I haven't checked the size, but I guess about 7-8mm [EDIT: this is correct]. Any help appreciated!

Hymnenoptera: Vespidae: Eumeninae: Ancistrocerus sp., male. This genus is very difficult to ID under microscope, almost impossible from a single picture. But in this animal i would say A. trifasciatus, 90% :-). Libor |

I found another view which adds a little more detail.

hmm, much better, but not the best view. In these wasps, the shape of 2nd sternum solves almost everything. But in general, this view supports my first ID. Libor |

Next time I'll shoot it as it flies over my head! Thanks again Libor  |
