Slovakia, Zvolen region, 700 m.a.s.l., village garden on plateau in hilly landscape, 27 May 2020, rather small Rhagio, approx 10 mm. I have possibly photographed this species before, but it was larger and there were a small difference in the appearance - this new specimen had yellow antennas, while the older (larger) ones from Great Fatra mts. did not. Except for this, all of them matched the description in M.P. van Veen's key: hyaline wings, uniformly dark pterostigma, thoracic dorsum with longitudinal stripes, yellow femora. My personal observation is a two-tone scutellum (grey base, yellow tip. The first coxa is slightly yellowish.

Hi treebeard, what about R. vitripennis? It seems the veins of the wings are slightly darkened? Eric |

@eklans - yes, I considered also R. vitripennis, but this species should not have yellow antennas while those from Great Fatra (with grey antenas) are larger. |

Don't rely on colour features in Rhagio too much, to me, vitripennis without any doubt. Wing pattern is distinctive. Theo |

By the way, is there any diagnosis of Rhagio montanus? I have failed to google it. |
