Hello In May last year I found, and catched, two horse flies. I have tried to find what species this is. The first horse fly I think can be Hybomitra bimaculata I will load three pics here so it will be easier to study the horse fly Is there anyone who can help?

Please, add enlarged pictures No. 2 and 3 of both specimens. From pics 2 I need to see structure of lower callus and the close part of subcallus. From pics 3 just antennae and palpi. I thing both specimens should be Hyb. nitidifrons confiformis. Did you got them in early spring? Libor Edited by libor on 13-02-2012 12:15 |

See small brownish-shinning areas under lower callus - an uniqie feature for European specimens of Hybomitra nitidifrons confiformis. Also your date of trapping agrees. This species is a really spring species. BTW: thanks for precisely photographed needed details. It is easier to try to get ID! Libor |
