I have found a medium-sized fly indoor(in my house)which I think belongs to Drosophilidae.However it is not Drosophila melanogaster and they are numerous around pomaces and food residues.Also their presence has last quit a long time from their appearance in my home(3 months). They do not attract to yellow or blue sticky traps and do not sit on poisend lures. Their costal vein is spinos somehow(only very short spines) but not long enogh to justify their belonging to Curtenotids.I want to the name of Genus and species they belong to?
