I caught this small fly a couple of days ago, trying to enter my house in the south east of England, via a small hole in the brickwork.
Any suggestions ?
Thankyou
Gordon

If you have the solitary bee
Osmia rufa breeding near your house, I suspect it is
Cacoxenus indagator, the drosophilid prasitoid in
Osmia nests.
