Hello Gumenuk Vitalij, Yes, a Chrysops. Looks like C. caecutiens with the black legs... Greetings, Ectemnius |

If I see well, the black markings on 2nd tergum is demarcated from the 1st and 3rd tergum by yellow color, so my opinion is the same still. Theo will arbitrate it Libor |

Hello Libor & Gumenuk Vitalij, I Incline to agree with Libor, as I have never even heard of C. divaricatus. Theo, what say thee? Greetings, Ectemnius |

I didn't response at first, because I agree with caecutiens. And not for Ectemnius' reason ! But it is very difficult to call, so I had a second look. In divaricatus, not only the black 'V' on tergite 2 is diverging (it is a V and not a U) but also it diverges more rapidly (so, it is a curly V). Tergite 2 is more white than yellow in divaricatus, as are the hairs on pleurae. Agreed, the spot on tergite 2 does not reach the hind margin of the tergite. In this respect, this spot resembles viduatus (whici has red tibiae of course). This happens once in a while in caecutiens, more so in sourthern regions. This form has been called ' f. ludens' in the literature. I must admit, it is quite difficult to judge from this angle and I had my doubts as well. Theo |
