On a tangent, how can you have perennial or annual as part of a key? How the hell do I know whether it's perennial or annual? Can you tell from looking? At least until I know better this seems quite bizarre to me. Not the first place where I think the key requires foresight that would mean you didn't need the key.
("Chalcid wasps (insects within the superfamily Chalcidoidea, part of the order Hymenoptera. It is one of the largest groups within the order, with some 22,000 known species, and an estimated total diversity of anywhere from 60,000 to more than 500,000 species, meaning the vast majority have yet to be discovered and described."
Oh lordy... and it might not even be a Chalcid I suppose. Some hints it might be a Eulophid wasp.They also have over 4k species - about half that of fish or birds!
Mind you some of the images of those wasps close up are simply stunning)
