hi Flyforum, This afternoon I found one of these Tachinidae sp. on a bark of a beech. place: Amsterdam forest. It was quite elongated and over one cm. The legs are also quite long. What kind of Tachinidae is this? Robert Heemskerk attached the following image:  [154.54Kb] Edited by Robert Heemskerk on 27-06-2007 23:53 |

Hi Robert, It's certainly a bristly fly, but the wing venation suggests it's more likely to be an anthomyiid

Owww..., I just see I made a fool of myself.. And when I saw these fly, I was surprised that 'this tachinidae(not) sp.' was so related to 'Anthomydae sp..' I didn't check it's wingveins..

During several hours I can't stop filling that I know this Anthomyiid with strong abdominal bristles. It is Eustalomyia! In most view angles it has more black/white thorastic patterns, but on some angle vague like this (compare with: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=6402 ). And so far, I met Eustalomyia only 2 times, but both times like this - sitting on tree bark. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I'm not convinced, Nikita. The photos show a fly which has an abdominal pattern that is not fixed - it will change depending on the angle from which it is viewed. Eustalomyia has a fixed pattern on the abdomen and thorax - with clearly defined black markings that look the same from all viewpoints. Tony ---------- Tony Irwin |

Well Tony, to tell you truth I'm not totally convinced too. But at least, I keep fly obviously similar to Robert's one collected 31 May on tree bark in Mosc reg. This fly is also large (more than 1cm) and elongate, with same strong bristles. If I look at fly from behind it has Eustalomyia patterns, if on 90 angle (as on Robert's photo) it looks as Robert's fly. It has short arista hairs as Eu.histrio and 7av on t3 as Eu.festiva. Someday I'll find answer... Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Tony you was right. I compared my specimens with Eustalomyia in Museum collection - a little bit resemble, but quite different. Still, I think I found answer - Leucophora sponsa, Anthomyiidae  Nikita Nikita Vikhrev - Zool Museum of Moscow University |

thank's a lot Nikita!, I have checked the name on the Dutch specieslist but I did'nt find it on the list? These are the Leucophora-species on the list: 1. Leucophora cinerea Robineau-Desvoidy, 1830 [soort] 2. Leucophora grisella Hennig, 1967 [soort] 3. Leucophora personata (Collin, 1921) [soort] 4. Leucophora sericea Robineau-Desvoidy, 1830 [soort] what do you think about that? Edited by Robert Heemskerk on 07-07-2007 12:54 |

1. Leucophora cinerea Robineau-Desvoidy, 1830 [soort] 2. Leucophora grisella Hennig, 1967 [soort] 3. Leucophora personata (Collin, 1921) [soort] 4. Leucophora sericea Robineau-Desvoidy, 1830 [soort] Hi Robert. 1. First of all thank you for this image. I collected this fly and immediately misIDed it as Eustalomyia  2. Genus Leucophora seems to me 98% correct, but I'll compare it with Museum material to get 100% 3. Leucophora sponsa is what I've got for my fly (attached image). 4. Your fly is Leucophora sp.

Yesterday I met another Leucophora male, again on tree bark, this time it was Leucophora grisella a species with long plumose arista.
