hi flyforum,

I was wondering what kind of fly this is?
Is Anthomyiidae correctly?

What do you think?
Is it possible to identify from this picture?

size: ~8mm
place: Amsterdam forest

Robert,

Robert- I am pretty sure it is Leucophora obtusa Zett. female. Luckily some of the bristles are visible, especially the rather long true ventral seta on mid tibia (photo 3), arista bare, no hairs on notopleuron, genal setae biserial, and very long dorsal setae on hind tibia. Also quuite a few setulae on scutellum

Hi Michael,

That's a nice unexpectedly contribution! :)
I didn't count on it.

And thank you much for your explination.

Looking at Leucophora in the Dutch specieslist, I cannot find Leucophora obtusa?

These Leucophora sp. are recorded in The Netherlands:
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]

L. grisella has plumose arista, cinerea has long pubescent arista, personata has some hairs on the notopleural area, and sericea has some long setae on the tip of the abdomen, which are admittedly difficult to see in the photo. L. obtusa has been recorded from Germany, France, Belgium and Britain and is relatively common. Of course one cannot record a species from an area from a photo, and my identification is just a suggestion, and an actual specimen could prove me wrong.

Alright, I'll keep the option 'Leucophora obtusa' open, and I'll say Leucophora cf. obtusa

thanks
