I believe this to be a Hyadina sp. but I can't figure out the species. Is anyone more familiar with Ephydridae willing to shine a light on this? Wilshire UK, 2021.08.17 Suction sample maico attached the following image:  [56.05Kb] Edited by maico on 12-05-2022 13:24 |

On balance I would say Hyadina guttata (should have clear patches either side of the posterior cross-vein, yellow palps, and two round dust-spots on the occiput)

Thanks, Tony. I just had another look and I can indeed see two clear patches on both sides of the posterior cross-vein. I had misread the key and was expecting it to look differently! Two round grey-dusted spots on the occiput too. I'll put this one down as Hyadina guttata. |

Does somebody know how valuable is the following feature, which is mentioned in Stuke (2010): * face golden dusted... Hyadina guttata (Fallen, 1813) * face silver dusted.. Hyadina humeralis auct., nec. Becker, 1896 Personally, I would say the face in these pictures is silver dusted (favouring humeralis), but that would contradict the clear patches (favouring guttata).
