This guide uses a combination of size, colour pattern and biological information to provide an identification key of 14 fairly distinctive species of solitary bees known
from Scotland. The key applies to female bees only: their male counterparts are often much harder to identify and are not discussed.  Most of the bees in the key should also be identifiable from good close-up photographs as long as their critical features are visible.

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.
