Rare, but very beautiful species in the area. Seems to be a species of shallow ponds that can dry-up easily.
I have seen a few females and males in 2006, 2008, 2016, and 2018, at Heinäsuotie, Maununlampitie, and Mattilanlahti.
Female with on each wing two large orange spots.
A male. The species overwinters once, as egg. So far, I found only one excuvia.
