Hello, While inspecting this dead fly (poor one - the upper antennae parts are gone) under the stereo microscope, I remembered a thread by Dima on the mating of yellow flies that Kahis identified as Meiosimyza (Lauxaniidae). The females thereby protruded two "translucent hornlets" flanking the genitalia. Possibly my fly had this ability, too, as there are such peculiar areas formed (see arrow). Also the hairs and bristles on thorax and legs seem to be comparable to Dima's flies, so I wonder if mine is a Meiosimyza, too.

Ok, not Meiosimyza. You will have reason. I can only compare with other pictures and unfortunately do not know what special features to focus on (otherwise I would not have to take so many photos!) Many thanks for reliable help, Sundew |

* No presutural dorsocentral setae * Spots on tergites - AFAIK no west european Meiosimyza has such spots Kahis |
