Parasitic wasp on mating Chalkhill blues

This tiny wasp was perched on the wings of a male chalkhill blue as it mated. Some kind of parasite at a guess.. Some Trichogrammatidae butterfly egg parasites are known to cue in on chemicals transferred to females by males during mating (they are attracted to the female after mating) and I wonder if something similar is going on here. Does anyone know of Chalkhill parasites?
