Hi, Recently we had an interesting discussion about black flies with big eyes (Bicellaria, Hybotidae versus Ptiolina, Rhagionidae), and I was sure to have one of them in front of my camera lens today. On the big screen, however, I saw that neither swollen hind tarsi nor antennae match. Also the thorax is not thus bulging. Instead, the fly looks like a Beris of Stratiomyidae. So can possibly B. chalybata be confirmed? Many thanks for help, Sundew Sundew attached the following image:  [187.24Kb] |

No Stratiomyid experts among us? |

Beris chalybata is correct.

Fine - thanks, Paul! The males obviously have much darker wings than the females. Regards, Sundew |
