This fly, with the spotted wings occurred in two traps last week. I looks like an Opomyzid to me, as does the other fly which was supposed to be holding it up so that the wings were flat but I see it moved. Anyway they are probably both the same family and that is all I need. I notice, but it doesn't show on the photo, the camera is not happy looking down the microscope, unlike myself, that both have branches on the upper side of the antennae only. I know this is a character of some Ephydrids, but???????????????? You all know how ignorant I am!:D

The one with marked wings is a Geomyza (Opomyzidae), not sure about the other, at a glance I'd have said Drosophila, the antenna wiill have a definite fork at the end if it is.
Hope this helps,
Sue ;)

Hi Gordon

Best to add '? Opomhyzidae' to the title of this thread, so that Jan-Willem will notice it.

Thanks Sue and Theo, OK I am happy with the first one being an Opomyzidae, I will post a new thread on the second.

Hi Gordon,

The first one is a female of Geomyza tripunctata.
