I think that they lay an egg right into the abdomen of the bee, where the whole life cycle takes place, rather than the egg being deposited on top of the bee and taken back to the nest to hatch out there. Fascinating flies, and very little known about some of the more unusual species, like the Myopae, and which bees they use.

Internal parasite

Thanks Ian - yes, I now remember seeing photos of hollowed-out bumblebees which these had emerged from. Have added a couple of clearer photos and amended text. I'll keep an eye out for dead bees now I know these are about.

Would like to find some Myopa spp but I think they are over for the year now.
