It looks like Xylota florum in the gallery, but there are similar looking species. Can somebody confirm or correct? Thanks, Marion Photo: Germany, Saxony, 15.06.2012 Marion Friedrich attached the following image:  [116.7Kb] |

Stubbs and Falk (in British Hoverflies) say: "... X. florum can be readily distinguished from the coeruleiventris/jakutorum pair ... In the female the spots on tergites 2 and 3 are orange, and the grey dust spots on the frons are pointed towards the middle and do not meet." "Another narrow-bodied European species, meigeniana Stackelberg 1964, could easily be confused with florum. ... In the female [meigeniana], the hind femur has only short erect white semi-dorsal hairs which are confined to a small area near the base (in florum there are additional longer erect hairs extending along the basal quarter or more). ..."

Thank you for the key, tristram. It is a pity that I do not have additional pictures. The spots on the frons do not meet, but I can´t see enough to evaluate the hairs on the hind femur. Marion |
