Found on hedge at Martlesham, Suffolk, UK on 22 October 2014. Please help identify the species. I can provide additional photos if that would help. Here is the fly before I captured it. Best wishes, Martin Martin Cooper attached the following image:  [142.39Kb] Edited by Martin Cooper on 25-10-2014 21:42 |

Although I can't see how long the row of pv on the hind femur is, the rest of it looks like Delia platura. The pv row should be short, about 3 distinct bristles near the distal end of the femur. The pinned lateral photo shows the origin of the species name, Greek for "flat tail." |

Thanks John. The specimen has dried with its hind legs rather close together making it quite hard to see the ventral sides; although I have something of blind spot for which side is which, despite efforts by Johanna to help me! Here is the image that I cropped to get the side view of the genitalia, which includes the hind femora.

Here is another fly which I think may be the same species, photographed at almost same place and time as previous specimen.

Excellent photos of Delia platura (what John already said..) Only the last one...a bit difficult to confirm if it is indeed also D. platura. Compliment for your effort! Johanna |

Thanks John and Johanna! I was surprised by those white hairs on the ends of the surstyli. They aren't visible in the lateral view but are quite striking in the view from below. Best wishes, Martin |
