I found two flies of this specie in the moss in mossy seaside meadow on the island Stord in Hordaland 19th of December. They were between 3,0 og 3,5 mm. Is this species known to any of you? Bjarte Aadland Bjarte attached the following image:  [118.79Kb] Edited by Bjarte on 20-12-2018 22:45 |

Are there any key for distinguishing the actual species of Crumomyia? (Most common in Norway is C.nitida,C.roserii,C.fimetaria and C.setitibialis). Bjarte |

I was thinking Copromyza (stercoraria?) In the first photo it looks like there could be 2 rows of postocular setae? Do you have a close up of the head from above? |

Agreed 2 rows, which means it can't be Copromyza as that has one row. Systematics of Crumomyia Macquart and Alloborborus Duda (Diptera: Sphaeroceridae) ALLEN L. NORRBOM and KE CHUNG KIM The Frost Entomological Museum, Department of Entomology, The Pennsylvania State University |

100% Copromyza the 3rd section of vain M looks longer than the 4th, so should be Copromyza stercoraria |

Hi, I wouldn't be so sure of the 100% Copromyza... Copromyza lacks the heavily infusctaed crossveins in the wing. Has a bronze sheen on the body. Has shorter bristles on the thorax. Since no postocular setae are clearly visible in the photo's or the surstylus I'd stick to Copromyzinae sp. Kind regards, Ectemnius |
