Hello, I always thought the pattern on the thorax of Maythropa florea very characteristic. But this fly hat the habitus rather of an Eristalis. What is it? Myathropa nevertheless? I found it some days ago near Cologne. Lenght was about 10mm. Thanks, Michael Michael Becker attached the following image:  [51.66Kb] Edited by Michael Becker on 22-05-2010 20:59 |

In case of doubt, look at the wing venation : Myathropa has an open r1 cell, Eristalis have a closed one (and even short petiolate). Here it is closed, so Ersitalis, plus the four anterior pairs of tarsi which are yellow : that gives Eristalis pertinax. Stephane. |
