Hi Switzerland, Altendorf, near lake of zurich, 430 m, terrace, 23.04.2023 Dark and very hairy. Face looks not much like Cheilosia ... I have no idea. Possible for ID? Thanks and kind regards, Brigitte brigitteu attached the following image:  [142.45Kb] Edited by brigitteu on 07-11-2023 20:46 |

It's not more than a guess, as photos of females are hard to find and I have never seen a Heringia: Heringia brevidens. based on van Veen (2010): Hoverflies of Northwest Europe and some information from Steven Falks website https://www.flick...442725613/: "and the frons with bands of black and pale hairs when viewed from the side" Edited by eklans on 04-11-2023 17:31 Greetings, Eric Kloeckner |

Hi Eric I have never seen a Heringia too. That is great and exciting found for me. Thank you for your reply to my posting! I'm not so advanced that I can work my way through a key, especially when you're not supposed to recognize and/or correctly evaluate something but I have the book of van Veen (2010): Hoverflies of Northwest Europe. The only thing I can see well are the antennaes. The Key starts with them and ends by Heringia (Heringia) heringi when the 3rd segment is elongate, 2-3 times as long as broad. I'll add a cut out pic of the antennaes. What do you think about? Kind regards, Brigitte brigitteu attached the following image:  [155.73Kb] Edited by brigitteu on 05-11-2023 07:18 |

Hi Brigitte, I'm not an expert and in my humble opinion van Veen's "elongate" means that the length of the 3rd segment is 2-3 times the height (see his figure 405). This correlates to the image of the female in Falk's site (+ the black and pale hairs!). Van Veen describes mainly the males so we should wait for an expert to agree or disagree. I'm confident that if it's a Heringia, it's not heringi because of the antenna. Not pubescens: eyes dark haired. Not verrucula: eyes (hairs) sparse, inconspicuous and pale (?) Falk: hairs more extensively pale in latitarsis and more extensively black in vitripennis. remain: brevidens and fulvimanus? Greetings, Eric Kloeckner |
