Hi, It looks like Phaonia, although there appears to be a hind leg missing the bristle on the tibia on the other side can be seen but I'm not sure. It doesn't seem to fit any that I know. 30th September on Ivy, near Lincoln UK. Janet blowave attached the following image:  [176.99Kb] http://cubits.org... |

Hi Janet, I think this is a female of Phaonia falleni/angelicae. Niels |

I've done some comparisons with P. angelicae, it has a few differences to this fly. For one, P. angelicae looks to have a pair of long ocellar bristles or in the region of the anterior ocelli. I can't see the halter on this fly, maybe it got broken? It's very obvious in angelicae. Another, P. angelicae has pv on the mid tibiae and I think part of those would be visible if they were present. This is one I named P. angelicae from 2010, I don't recall posting it for ID but I might have! blowave attached the following image:  [187.58Kb] http://cubits.org... |

I found photos of what looks to be the same fly from two days previous on 28th September. From what I can see this looks to be Phaonia scutellata. All black palpi and antennae, 1 pair pre scutellar bristles, p bristle on t1. Does anyone agree? blowave attached the following image:  [179.93Kb] http://cubits.org... |

I see 2 probable species Phaonia angelicae or Phaonia erronea. As I can't see whether the mid tibia has pv or not, I can't affirm anything. I can't judge either whether the mouthedge is enough protruding or not for P. angelicae.

Thanks Stephane, I have cropped off and lightened the mid leg of P. angelicae which is at a similar position. The pv are easily visible on this..

OK, no pv bristle visible. Is it really absent or broken ?

Stephane Lebrun wrote: OK, no pv bristle visible. Is it really absent or broken ? Good question Stephane, there is also an apparently missing halter on the fly in question unless it's the dark blob I can see on the anterior edge of the calypters. I checked the keys for female P. erronea, t1 doesn't have a posterior bristle. The hind femora have a complete row of strong anteroventrals too. I guess the keys are correct and not referring to a previous incorrectly named fly? From reading older threads I have realised there is a difference in the frons at the vertex, the keys for P. scutellata states it is 1/3 of the total width of the head. What is the reason for it not being scutellata? http://cubits.org... |

Sorry Janet, I don't understand any more of which fly we are talking, which is which ? Photo 1,2,5, 6, 7, 11 : difficult to ID (OK some pictures show a small pd on t1, which P. erronea has rarely (but not never). Photo 3, 4, 8, 9, 10 are likely Phaonia angelicae (because we can see pv on t2 or additional pd in basal part of t3). Stephane. |

I had mentioned for photos 3& 4 it was one I had named P. angelicae, I posted it as a comparison when niels suggested it could be this or another. Photo 10 I have also mentioned it as being angelicae, the others I think are all the same fly but taken two days apart. http://cubits.org... |
