Hi, It looks like Campsicnemus, and it keys to Campsicnemus paradoxus but I might have got the genus wrong. Campsicnemus paradoxus is not on the UK list either unless it's got another name which I can't find. It was inside on my window on 11th September, near Lincoln UK. Size ~5mm I've had to crop the photos down a lot as I can't get them within the max. kb size.

It is not Campsicnemus paradoxus that has 1.5 mm body and short postpedicel. It looks like C. mammiculatus: See Parent 1938. Please compare leg setation of your strange fly. Igor Grichanov |

Thank you Igor! Should I be excited? There's nothing at all about this species on this site, it's not listed in the UK unless it is under a different name but I still can't find one. Fauna Europa gives the location as all over France, it must know where the borders are!  http://www.faunae...on1=135300 The list of Campsicnemus for the UK.. http://www.dipter...hp?id=9392 The references I found were to Parent 1929. http://cubits.org... |

I tried to check the pdf Paul, it got stuck halfway so I refreshed, it eventually came up but there was an error so I had to reload it. I got to page 27 with some difficulty, that was as far as it was going to give me! There goes my daily usage Mb.    I guess there's a nice drawing showing that wonderful leg which I got the fly to pose for me?

I have UK records of C. scambus in June, July, August and September, latest being 23 September.

Leg colour can be variable - structurally this looks like scambus, so that's what I suggest it is, unless its genitalia or DNA don't match!

Igor usually knows his Dolichopods so I would like to know what key features would not fit C. scambus. I have looked at keys and the leg colour doesn't say it's that variable for scambus. The size is also much smaller for scambus, 2.5 to 3.25mm and it certainly wasn't that small. I'm usually quite accurate at judging size. Keys state: Legs reddish-yellow, sometimes partly brown..............................................10 10. Mid tibia considerably dilated and curved, anterodorsally with a row of long bristles on apical half; fore legs bearing long hairs; 2.5-3.25........................ ......................................................................................... scambus (Fallén http://www.dipter...Europe.pdf I have found a few photos on here of C. scambus and they all have yellowish to partly brown legs. The key also states for mid tibia " row of long bristles on apical half" which mine has but it also has some longish bristles on the basal half. I have checked all the males I found on here and none of them look to have the same bristles on the basal half. The shape of the mid tibia also looks a little different to me. http://dolicho.na...ambus3.jpg http://cubits.org... |

I have a large scambus from 11 October that has leg colour nearly as dark as yours. It measures 3.5mm. Remember that length excludes wings and antennae.

Melanistic form of Campsicnemus scambus was my first thought. However, scambus has quite distinct and rather long process on apex of mid basitarsus. In addition, next two segments are long setose in scambus. I do not see these armarments on your photos, Janet. Would you kindly show mid tarsus under different angle? Regards,

I can well envision the required parts of the mid leg being positioned in the wrong way to see the apical proces of the mid basitarsus en the setae on the second and third segment (too dorsal). However, according to Parent's (1938) illustration the terminal second to fourth segment of the fore tarsi of mammiculatus should be long setose ventrally and I think the position of the fore legs should have shown that if it were there.

I only kept the best 4 photos Igor! Imagine trying to take photos of a small fly running up and down a window, with me squatted on the kitchen sink trying to takes photos! It may have been smaller Tony, I don't take into account wings etc. but when you can't see the abdomen well it can make the difference. I have cropped the photo from behind which shows the mid basitarsus best, it looks to me if there was a "distinct and rather long process on apex of mid basitarsus" it would show in this shot. I have also cropped one of the semi-side views which might show the front tarsus better, it looks like it could be "long setose ventrally" in the sections Paul mentions but I don't know how long they should be. blowave attached the following image:  [144.99Kb] http://cubits.org... |
