Workshop presentation given by Juho Paukkunen at the BWARS Members' Weekend 2019. The presentation outlines key characters for separating the 13 British species of the cryptic Chrysis ignita group. Juho cautioned that colour characters given in the Nordic and Baltic Chrysididae key (Paukkunen et al., 2015) are not reliable for British specimens:

Juho Paukkunen, Alexander Berg, Villu Soon, Frode Ødegaard and Paolo Rosa. 2015 An illustrated key to the cuckoo wasps (Hymenoptera, Chrysididae) of the Nordic and Baltic countries, with description of a new species.

Key to Wasps of the family Vespidae - corrected version 4
Issued 26 September 2019

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

The correction relates to one character which had been transposed in the male Dolichovespula part of the key.

Male Vespula are now excluded from the key as it has become apparent that more work is required regarding separating the species rleiably.
