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.
