Hello!

I was just examining some older photos and would appreciate your opinion(s) about the identifications. Thank you very much in advance!

All photos were taken here in Ostwestfalen/Germany.

The first beautiful, violet-blue fly with banded eyes I found on May 30, 2003 on a wood clearance. Could it be Heptatoma pellucens?

Here a male and a female Tabanus ("normal" size, 15-20 mm):

Can all these flies be assigned to Haematopota pluvialis:

Dear Juergen


Horseflies again !

Your male Heptatoma is correct.
The male Rinderbremse is not bovinus, but probably autumnalis.
These males can be very reddish on abdomen.
The female Rinderbremse is probably more a Hybomitra

The first Haematopota is not pluvialis, most likely crassicornis.
It is much to dark.
The seond could be correct.

Please understand that the ID of Hybomitra and Haematopota from pictures is very difficult. One needs top quality pictures, preferably more than 1 from different angles.

So please keep sending in, these horseflies

Hello, Theo!



Thanks a lot for your help! I hope I get a new (better) camera before the diptera season really starts (although even on sunny days now in winter there are nearly always some Nematocera and flies on the wing :-)).
