I found some of these flies from end of May until now on a dead aspen in Germany, Saxony. I guess Hammerschmidtia ferruginea. Can the species be confirmed?

Greetings, Marion

Wow - that looks interesting! In the Red List of Hoverflies of Saxony (https://www.natur...liegen.pdf) as well as the complete list of Germany (https://www.rote-...html#idx_h), the species is considered to be threatened with extinction. To reproduce successfully it needs recently fallen, mature Aspen logs. In the middle picture the female is ovipositing, so this log should remain on its place, which nature conservation workers should ensure.
I think your identification is highly probable, even though Hammerschmidtia and brown Brachyopa species are easily mixed up. In May I saw B. cf. testacea that looked rather similar but not fully identical. According to the key https://www.resea...E-2020.pdf Hammerschmidtia differs from Brachyopa as follows:
- vein R4+5 with apical section longer than crossvein r-m
- hind tibia with short strong black spines on anterior surface
- mesopleural anepisternum, postalar callus, and scutellum with strong bristles
- face of male with tubercle
The wing venation isn't depicted well in your photos, but I see strong bristles on the thorax and, in the middle picture, there might be spines on the hind tibia. Also the tubercle of the male face is visible.
Falk (https://www.flick...382148394/) shows only males, but they look very similar.
You should contact Dieter Doczkal to get an expert opinion and perhaps some advice on where to report and publish this find. If the species is really so rare and endangered, this could perhaps be used to justify the designation of miniature protected area (Fl├Ąchennaturdenkmal).
Much luck and best wishes, Sundew

Hi, I can confirm Hammerschmidtia ferruginea. The species meanewhile spread to northern Germany and established in forests without any mature Aspen.

Love it!

So hopefully my 13-years-old male in the gallery soon can finally end its desolate period of singledom. Wink
Best greetings

many thanks for the detailed contribution with links and key and the confirmation of ID.
Rupert, I asked my females and they agreed to visit your Methuselah.
Best wishes, Marion
