Thread subject: Diptera.info :: Tachinida sp.
#1
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?
#3
Hi Robert,
It's certainly a bristly fly, but the wing venation suggests it's more likely to be an anthomyiid

#4
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.

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.

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 7
av on t3 as Eu.festiva.
Someday I'll find answer...

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

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?

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.
