Thread subject: Diptera.info :: Acalypterate ?

This fly is very distinctive with its fat abdomen. About 5mm length, swept from riverside, 14 July. It has no post verticals (that is verticals directly behind the ocellar). It has a pair of crossed innner frontals just in front of the ocelli (if inner frontals is what these bristles would be?)
I can't even decide for sure if it is acalypterate!!
Keying it, I reach Piophilidae, which does not seem right.
What family is this fly?

This is actually an anthomyiid - Myopina myopina
. Nice one to get!

Blimey - it does not look anything like the usual Anthomyiidae and threw me completely! Thanks for that Tony.
Is it a riverside species do you know?

Yes, I've taken it by rivers and by lakes - not sure that the larval stages are known. Mike Ackland would be pleased to get the record.

Thanks Tony. I'll send details to Mike.
