On the 1st of July by the edge of a field near Great Brickhill, buckinghamshire, England. I was thinking Chrysotoxum cautum or maybe verralli. |

Nope, not cautum, on the second picture it's clearly visible that antennal segment 3 is shorter than segments 1 and 2 together. So it's Chrysotoxum verralli indeed, which also fits better it's general shape and color! greetings Greetings, Gerard Pennards |

Hello Steve, Yes, i't proves my point. I took the liberty to work your picture a bit, you see antennal segments 1, 2 and 3. In cautum 3 should be as long as 1 and 2 together, which clearly isn't the case. 3 is much shorter than 1 and 2 combined. So it's a female Chrysotoxum verralli!
