Location: Midwest Sweden
Date: 2007-MAY-06
Habitat: Found in garden

Hard to see any details on this black fly. I first thought Lonchaeidae, but I doubt it. The wing venation etc doesn't fit? It is probably some other strange family ... ;)

Edit: Changed subject (Small black sturdy glossy fly)
Edit: Changed subject (Berkshiria hungarica)
Edit: Changed subject (Berkshiria albistylum)

Another view.

Stratiomyidae - Pachygasterinae.

the very transverse head with broad frons and, it appears, pointed flagellum, suggest Berkshiria hungarica.

Stratiomyidae crossed my mind due to the broad abdomen, but it doesn't look like the common ones so ... Thank you very much Jere and David. Berkshiria hungarica! - Mmm, cool name B)

Note that it is a redlisted species (NT = Near Threatened) in Sweden!

Ahh, I see. Nice find then ... :D

Do you have old/dead aspens (or other Populus trees) in or near your garden?

Yes, there are aspens. All sizes I think. Some felled by beavers, near the garden. No other populus as far as I know.

Nice species, it is a female but the species name is now Berkshiria albistylum Johnson, 1914, because it is the same species as in north America, and the older name is from there... Very nice find,,,

Thank you Martin. I'm wondering what Kahis is going to say about this fly and aspens :)

Swedish dipterist Hans D Bartsch says the name should be Berkshiria hungarica, and so does Fauna Europaea. I'm submitting it to gallery as B. hungarica.

I really wonder what is the proper name for this species. Rozkosny synonymised hungarica with the N. American albistylum in his Fauna Ent. Scand. book, but apparently this has not been accepted. I asked Dr. Woodley (the author of the World Catalog of the Stratiomyidae) why the synonymy is not accepted in the catalogue; he told me he as unaware of the synomy at the time:o.

Very confusing :(

As an absolutely unbiased person I vote for the name hungarica to be preserved :))))))

Rozkosny retracted his statement after Krivosheina (1979; publication in Russian) stated to have found a number of distinguishing characters between Nearctic and Palaearctic specimens. Rozkosny published that in his treatment of European Stratiomyidae.
