I have posted a couple of types of this bee but as always with these an id could only be confirmed with there being 16 types of this bee and many looks the same .. so if you look at all my Sphecodes bees they are different that alone cant give an exact ID.
Sixteen species are recorded from the British mainland with another species found on the Channel Islands. Sphecodes are cleptoparasites of other bees in the genera Lasioglossum, Halictus and Andrena. For many males, examination of the male genitalia is essential for accurate identification, and this needs to be pulled out when pinning fresh material. There is much scope for improving the understanding of Sphecodes-host relationships in Britain…. Steven Falk
