Fly on Primrose

Yesterday we found a large patch of Primrose flowers and nearly every one had one of these flies on either the leaves or the flowers. I didn't see them on any other flowers so I assume they specialise on Primroses. This was in mid Sussex on a sunny afternoon. Any help much appreciated!

Re: Fly on Primrose

A species of Bibio, which are widespread at this time of year and probably just coincidence that you were seeing them on primroses, though I have noticed they will collect on yellow flowers of gorse, as well. Likely to be B. lanigerus from the look of it, but best done to species via a specimen.

Re: Fly on Primrose

Are there keys for Bibio?

I'm seeing quite a few which rather look like B. johannis to me but I'm only guessing really.

The Royal Entomological Society key to Bibionidae and Scatopsidae (by Freeman and Lane, 1985) is still available (slightly damaged stock) - £2.00 plus postage
