Northern Germany, Schleswig-Holstein, Schenefeld near Hamburg, at an uncultivated natural area near a small rivulet, 25 m, Outsidefoto (only this pic): kuv, 22th of June 2013. Is my idea correct? Please help to get the ID. Kuv Edited by kuv on 16-03-2015 09:28 |

If those are hairs on the eyes could S. torvus if you get them where you are? |

Thank you very much Dave -  . To check whether I have understood you in the right way I first put an enlarged pic of the hairy eyes to the thread. And second I can tell that S. torvus is reported in whole Germany (where I found the fly). Best regards Kuv |

Hi Kuv, Fine white hairs on the eyes themselves are used to differentiate S. vitripennis and S. torvus in the U.K. S .torvus flies early so if no other Syrphus with hairy eyes in your area then should be fine for torvus. (Sorry don't really know continental Hovers as yet. Dave |

Thank you Dave. Unfortunately both, S. torvus and vitripennis fly here evidently from March to September/October in several generations. As I don't know whether the eyes at the second pic are "hairy" enough I 'll change the headline of this thread hoping somebody knows exactly ... Best regards Kuv |

Eyes are hairy enough, not so dense in females, eye hairs not in vitripennis; meant that I was unsure if other Syrphus in your area may be similar |

Thank you Dave once more. As I found a key where the difference is called "numerous hairs -> S. torvus" to "some very short scattered hairs to other like S. nitidifrons" I think it is best to say for my fly "S. cf. torvus". Best regards Kuv |
