Is it possible to tell species of this 4-5 mm long fly from this picture? Looks like bicolor but I think it is not. Photo from Hörsång, Ångermanland, Sweden 62.56N 17.47 E 22 october 2009 Thanks for your help in advance Regards Kurt Holmqvist kurt attached the following image:  [96.19Kb] |

Nice one for the study... Midtibia with 1 ad Hindtibia seems with 3 ad Calli yellow + scutellum with tip yellow + abdomen yellow. Pegomya seems right, maybe winthemi Joke van Erkelens  |

Difficult for me to say...it is for sure...(only study Antho.), but i don't know any other Anthomyiidae with the combination of calli+tip scutellum+abdomen yellow. Only the palpus has to be yellow also and it seems to be dark, but could be yellow in a different light, also the last 3 segments of mid and hind tarsi has to be laterally expanded......it seems so, when i look at the first and last photo. Pegomya cf. winthemi i would say for now...  Joke Edited by javanerkelens on 22-10-2009 21:37 |

Joke, I'm not ready to give name, but I can give an advice: "Believe your eyes, do not believe what you desire" I mean: anterior frons yellow, legs yellow, abdomen yellow, but palpi are black, either you like it or not!

The female of Pegomya winthemi has expanded last tarsal segments on mid and hind legs, quite distinctive. I have had several in the beer trap I'm operating. Very easy to recognize.

See http://www.dipter...d_id=17447. You can see the dilated tarsal segments in these pictures.

Thanks to all of you looking at my pictures. If I understand you this is not even a Pagomya? Kurt Holmqvist |

I have study again the Key and found out , that there are indeed more species with more ore less yellow calli + tip of scutellum+ abdomen. And also more species within that group with the tarsen more or less expanded. (Pegomya winthemi / furva / circumpolaris / fulgens / transgressa) So there are more specie possible, instead of what i sad before... I found yesterday evening problaby a Pegomya winthemi myself (Photo ) and indeed we can see the nicely the hind tarsi laterally expanded. But....about your photo's, i think with the knoledge i have now, i find it difficult to say more.... But i have learned much more and hope for you also....

Thanks a lot joke. I think that many users of Diptera finds your description interesting. At least many amateurs like myself without keys. Thanks one more time Kurt Holmqvist |
