Noted on iNaturalist by Jere Kahanpää as having irregular markings... "The interrupted yellow bands are quite atypical from an european point of view" So thought I would double check here. In Iceland we only have two species known on the list S.ribesii and S.torvus. Observed 22nd May 2023 in Reykjavik. iNaturalist post : https://www.inatu.../163168856 : sbushes attached the following image:  [156.79Kb] Edited by sbushes on 23-05-2023 15:04 |

Yes, it should be S. torvus, which is listed for Europe, Asia to Japan and Nearctic (Hoverflies of Northwest Europe, van Veen, 2010). If you want to triple check: Femur 3 should show: tip with short adpressed black hairs & black on basal ¾. Greetings, Eric |

Thanks Eric. I will post another observation from that day which shows the femur. |

I wonder if not the the legs are too dark for Syrphus. I'd look into Parasyrphus. |

The only Parasyrphus on the Icelandic list is Parasyrphus tarsatus. Is that an option? What's diagnostic of that species? Other observations of hoverflies in Iceland have been noted as being dark on iNaturalist. When I raised this with Erling Olafsson at the National Institute here, he said it was very typical for Icelandic specimens that they would be darker than their continental equivalents.
