Hello, In the South of France, April 21, 2015 A Chrysotoxum but I can't quite evaluate the length of the articles 3 and 1-2 of the antennas. I also wonder about the last abdominal segment! Thank you for your help Liliane D attached the following image:  [185.32Kb] Edited by Liliane D on 15-09-2020 19:12 |

The length of the articles is difficult to evaluate but what does the shape of the last abdominal segment mean? |

Well, it's really hard to evaluate, but the hind margins of tergite 4, 5 are yellow, the hairs on the sides of tergite 2 could be white? And if length article 3 = 1 + 2 it's C. cautum which can be seen in April. Greetings, Eric |
