I have my doubts. Is it not Hybomitra lundbecki ? (Lower callus large and shiny black ?) Theo Zeegers |

Well Theo, yesterday during 10 minutes I was attacked by two horsefly in same plase. Both, instead of dinking my warm blood were collected, one of them also photografed. By quick glanse I decided that both horsefly looks same and than checked one of them by key and got H. bimaculata. After your reply I recheck both, one with greish general colour and t3 brown with black top is realy bimaculata, I think. Another one, more brownish, eyes more greenish, with t3 yellow with brown top (on image), so has to be H. lundbecki. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hi Nikita I think you are right. Very green eyes is typical for the montana-group: montana, tropica and lundbecki. Beware, however, that the colouration of the eye might depend on the angle you are looking at ! With a real lundbecki, the difference in colouration should be obvious. Males of lundbecki are one of the few species that hover frequently and consistently (others: arpadi and muehlfeldi) Theo |
