Hello,
Today we obtained this fly from a cynipid (wasp) gall from Van. It is about 2mm length. Its ID will be very much appreciated.

Leucopis sp., so yes, Chamaemyiidae. Usually only males can be identified reliably, on the basis of their genitalia.

Paul is right - Leucopis. But it's emergence from a cynipid gall would only be right if there were aphids in the gall - none are known from anything except for sternorrhynchans. So this is definitely not a predator of the gall wasps.

During a survey on the cynipid galls of S.E.Turkey, we obtained on 28 Febr. 2010, during winter, a gall Aphelonyx persica Melika,2004 from a dried oak stem. We obtained from other cynipid galls of oaks, numerous cynipids or parazitoids (chalcidids, braconids, ichneumoids). But this time -today- we obtained this Leucopis species. We are aware of the relationship with aphids. But at the present time, the aphids never developed due to the cold of winter. The gall mentioned above with the short oak stem was well protected singly and separated in a plastic box. Reason of the appearance of Leucopis may be hidden in the bionomy of the species in the last autumn.
Thank you Steve, for your kind attention to our short information on the gall and Leucopis.
