This fly was identified as a male Anthomyiidae and a possible Lasiomma seminitidum on the Danish site Fugle & Natur. It was seen in Aalborg, North Jutland, Denmark on March 20th 2014. Size about 5 mm. Can anyone confirm the species ID? Are there other possibilities? Thanks Line Sabroe attached the following image:  [174.1Kb] Edited by Line Sabroe on 11-02-2015 19:21 Line |

Lasiomma seems right! There are a number of possibilities; L. anthomyinum, L. seminitidum and L. strigilatum. (all with the eyes haired and present in Denmark and on your second photo we can see those haires) L. anthomyinum with the eyes long and dense haired, the two other species more sparse haired. In L. anthomyinum the hindtibia with about 6 av. In L. seminitidum / strigilatum the hindtibia with about 3 av. If I look at the second photo, I don’t think there are 6 av present on t3. L. seminitidum has de costa haired ventrally and the hindfemur with long pv setae. L. strigilatum has de costa bare ventrally and the hindfemur with only short fine pv setae. Conclusion: we can’t see if the costa is haired or bare ventrally and we don’t have a good view on the legs chaetotaxy (hindfemur and hindtibia)…. Lasiomma seminitidum is a very common species in most countries, more common as L. strigilatum. So….there is a good change this could be indeed L. seminitidum, but I can’t give the full 100% to it.

Hi Johanna Thank you so much for the detailed explanation of key characters. This next image is the best I could find showing the hind leg. Does that make any difference? Line Sabroe attached the following image:  [196.88Kb] Line |

On your last photo we can see the long pv on the hindfemur, so ..... Lasiomma seminitidum, it seems to be. Johanna |

Thank you. I know it's hard to be completely sure based on photos like these (not so detailed ones). Two different people coming to the same conclusion does give it a bit of weight, though. Best wishes Line |
