This photos were take on 29th May 2021, on a field maple hedge in an garden (Lüneburg, Niedersachsen, Germany).

But maybe we have a little chance if you look at the original images to find out if the "Tarsomeres of fore tarsus posteriorly with elongated, somewhat curled hairs" (from: A Revision of Oriental and Eastern Palaearctic Species of Metopia, By Thomas Pape, Copenhagen). Greetings, Eric Kloeckner

In any case, it is a common species definitely present in NS. As for the ID, I agree with eklans. The contrast on frons between white and dark is less extreme than in argyrocephala, a clear indication that this is staegeri. Theo

Many species were not published any more since the 1930s. At the moment, there are only two Metopia species on the list: Metopia argyrocephala and Metopia campestris, with the last records published in 1939 in both cases. I add a magnification of a part of the original photo, but I think the sharpness is not sufficient. Jann Wuebbenhorst attached the following image: [118.64Kb]

Do you think this record of M. staegeri has enough evidence to be included in the paper? Greetings, Jann

Member Location: Northern Germany, Lower Saxony Posts: 568 Joined: 10.03.17	In Stuke (2019), there are only two Metopia species listed: M. argyrocephala and M. campestris - the latter only mentioned for the 1930s. And in the Updates (http://www.conopi.../styled-2/), Metopia is not mentioned so far. Jann
