I saw this individual on hogweed beside the River Lyd, in Lydney, Forest of Dean on 4th August. I think it may be a Melangyna, possibly umbellatarum.

Is an id possible from these photos? Thanks

My experience is that M. umbellatarum when alive has creamy coloured spots. M. labiatarum has the more citrus yellow spots (M. compositarum is recorded as being more northern).
I always have to go through the keys though, as I cannot identify them on sight, and there are microscopic characters which I need to differentiate related species.
Whilst all Melangyna are described, not all are illustrated in Stubbs & Falk.
