At first, nice photos! I have doubt about the dorsal preapical setae on the hindtibia. I can't see clearly if there are three or two long preapical setae. It almost looks if there are three equally long dorsal preapical setae, what could mean...Pegomya bicolor. If two...than P. deprimata indeed becomes a possibility. I show you the precise position of those dorsal preapical setae... Johanna javanerkelens attached the following image:  [148Kb] Edited by javanerkelens on 01-06-2014 20:46 |

Thanks for your comments and interest Johanna ! I would say 2 long dorsal pre apicals, the "red one" shouldn´t be dorsal ? skrylten attached the following image:  [199.74Kb] Edited by skrylten on 01-06-2014 21:36 |

Indeed seems the 'red' one more on the ad site. So, with only two posterior preapical setea, we have to look if the other characters will fit to P. deprimata: Occiput without any pale hairs ventrally = correct Frontal vitta with cruciate interfrontals = correct Hindtibia with only 2 ad = seems correct (not 100% good visible) Postpedical dark = correct Face almost flat = seems correct (lower margin of head in profile shorter than length of head at level of lunule) Parafacial in lateral view very narrow = seems correct But I can't see if the lower katepisternal seta is only about 0,6 times length of upper katepisternal........if this also is correct, than we can assume this is indeed a female Pegomya deprimata (Zetterstedt) javanerkelens attached the following image:  [159Kb] Edited by javanerkelens on 01-06-2014 22:21 |

It don't think it is P. deprimata or bicolor. P. deprimata has a dark abdomen with greyish dusting, larger postpedicel reaching to mouth margin. The ventral setae on hind femur are also much too strong and long for female deprimata. There are quite a few Pegomya species in Sweden, not found in Britain, which are little known. I will post a couple of photos of what I think is deprimata when I have taken them, be a few days time. |

Photos are a female of Pegomya deprimata collected in S. France with males. The hind tibia in Skrylten's photos have some extra setulae anteroventrally in apical third, which are not present in my deprimata female. Note the shining black tergite between 5th tergite and cerci (?6th tergite) Pictures did not appear! Edited by Michael Ackland on 02-06-2014 17:04 |

Interesting what you can find in a vase (it showed some signs of life when it dried) ... If the fly came with the flowers its a possibility that it is not from Sweden (we import a lot of flowers from the Netherlands but I don´t know the origin in this case). I remember the 6th tergite as shining black but only have this poor single photo ( I can take more if it will help). Can I do more to get further, or is this a "dead end" ? skrylten attached the following image:  [191.06Kb] |

Michael asked me to upload some photos of Pegomya deprimata. On his opinion it can't be P. deprimata because of the numerous pv-setulae on hind tibia towards apex Unfortunally I don't have P. deprimata in my collection, so I can't check.......but, I can't see any pv setae on your photos of the hind tibia ??? Or do I need new glasses javanerkelens attached the following image:  [74.84Kb] Edited by javanerkelens on 02-06-2014 20:39 |
