It looked rather brown to me, thus I was unsure.
Also, the dumbbell shape of the distal white spot I found not convincing, as I was imagining it could also be a combination of both wings, the underlying spot from the other wing shining through.
Lastly, I am confused - according to GBIF,
lacustris is a synonym of
stagnalis - not of
tenuicosta, as I was assuming.
