Imago. Male. Some 7, I think, were reported a good week ago, and I had to go. A new species after all, and being the only reliable place in Denmark to get it.
Unmistakable when seen well. Rather confident when perching in the bushes alongside the western shore of the lake (only part accessible). I estimated to have seen 3 males in all and no females.
Imago. Male. When seen well only possible to confuse with ultra-rare Lilypad Whiteface, but Dark has white mouth parts and Lilypad male, seen from above, has whitish wing marks where Dark has them black on both upper and lower side of the wings.
Imago. Male. Four different photo sets of males this day doesn't mean that I saw four individuals, but that I managed four different shooting sessions. Scrutiny will very likely reveal some of them the same.
