Thank you for the key. Using this I am down to M. tesselatipennis/pellucida, so it is down to the colour of the palpi and structure from the snout (with the latter not visible in my photos). In the additional close up I am attaching the palpi have different colouration, depending on the angle. The one straight on looks brownish, the other, from the side looks. lighter at the base with a darker tip. Edited by sylvester_k on 20-08-2020 21:45 |

Photo 3 does not show the same fly - there are no wing spots, no spots on the femora, and the thorax hairs are much shorter! Therefore the cropped photo 5 is not helpful. (I suppose it is a Sicus spec., possibly ferrugineus.) This said, it remains difficult, but M. tesselatipennis might be a rather good candidate. Compare the species descriptions by Falk (https://www.flick...279506405/) and contact our member John Smit who wrote this nice Dutch key: https://www.eis-n...;TabId=563. Regards, Sundew |

Hello Sylvester, Volker & Sundew, Myopa are not always easy to identify. But the 3rd photo does indeed show a Sicus sp. The feature of the palps is not always easily judged, because of lighting circumstances. The best features to look for in M. tesselatipennis group specimens is the hairlength on the badomen, and the markings on the pouter edge of cel R. Here the hair is short and the wing markings are clearly broken by a white patch. -> Myopa tesselatipennis! Kind regards, Ectemnius |

Regards, Sundew Thank you for your helpful comments. I thought there was something suspicious about this photo, since the wing markings were looking different and thought it had to do with the angle. These are the pitfalls of field photography. I am removing the Sicus photos. |

I am adding another photo with a better view of the wings and the abdomen hair length. Sylvester Edited by sylvester_k on 23-08-2020 10:31 |
