20th of June 2023, I see my first Haematopota sp. male ever. In Kragelund Moor, Vejen, Denmark.
I tried using key in "Families of flies with three pulvilli, 2022", and came to the conclusion that it was H. crassicornis. I reverted back to sp. though soon after.


Now I visited the area again 11th of August, and perhaps on the same fence post, saw yet another male. This time I got better photos. The eyes were all whitish grey at top, while the June observation had some brown mixed into the bit darker grey eyes. Perhaps the same individual?

Stunned to get a nice view of the underside of the eyes.

A side view with bad focus.

I should think this is H. crassicornis.

Thank you for looking.

Hi Erland, I think you came to the right conclusion!

Thank you very much Eric.

The site is interesting for Tabanidae, as the are all-year graazing animals of water buffalo, horses and cattles, and even boar (Hungaryan breed). Kind of a private rewilding project.
Saw male Tabanus automnalis and female T. bromius too at my first visit.

greeting, Erlamd

I don’t see any yellow hairs on vertex, so I don’t think so.
Colour of antenna is very difficult to assess.

Abdomen colourwise is typical pluvialis.
Also end of August is hardly possible for crassicornis.

Thank you very much for looking at this male Theo. All my photos of the genus are more or less put at genus level, and my attempt to key this one, seemed a bit like guesswork.
