Back from holiday I find these beautiful horsefly pictures. I have little doubt that, given the locality, the species is A. rusticus. They can be quite like latistriatus. Have a look at Alan Stubbs'plates and you will find a clear rusticus with a pair of dark vittae on tergites. The males can have quite large yellow lateral spots on abdomen. Theo Zeegers |
