hello...I took a picture of this fly on 23-03 in Voeren on a riverside.
At first I thought that this must be another specimen of Liancalus Virens. I had found one of these a week earlier on the same spot.
But here on the thorax only one stripe is to be seen, whereas L. virens certainly got two stripes.
The dots on the left and right side are the same, but the "only" one stripe puzzles me.
And there is one cross vein in the wing that seems different as wel...
but, I am just an amateur, so please correct me if i'm wrong..and thanks for looking into this :)
