Hello Pentti,

how many ad on t2? i see one but is there a smaller one above it or not?
it is of the rudis group. check the underside of the wing to eliminate pediculata.
if one ad, then angustigena male.

edit: it can't be rudis, the long av hairs between av setae of t3 are missing.


Best wishes,
John

Hello Pentii,

I should've spent a bit more time on the photo labels. I've made a new photo with better labels.

Best wishes,
John

Hello Pentii,

I apologize for the sloppy photo labels. I am tired and i have Bronchitis. I tried to hurry and slap it together.

Anyway, it looks like a good match with Pollenia angustigena. You can check your specimen against the work of Dr. Rognes:

Best wishes,
John

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
