From Lasiocampa quercus larvae collected last summer in southern Sweden, and stored outdoors, these flies came out this April. To me it is Ceromya bicolor. I have received 3 flies sent to me, and none of them have subapical scutellar bristles convergent! But what else can it be? 5 mm The anal vein does not reach the wing margin. Lower st shorter than the antenior. The r4+5 vein with bristles continue more than half the way further from r-m to the wing edge. Sorry for bad Pictures. amaira attached the following image:  [171.4Kb] Edited by amaira on 02-05-2021 09:22 |

Yes, I agree. The subapicals might have been distorted while pinning. it seems to be a female, if so: the large last tarsomere of front leg is distinctive for female bicolor. Theo |

Fifth segment much longer (nearly twice) as fourth. Looks good to me. Theo |
