- This year, for the first time I observed a few Keisarinviitta (Argynnis paphia) butterflies. Spectacular, especially since I observed the species for the first time in my life during my holidays last year in the Pyrenees. The butterflies where present at one single location and seemed to prefer to stay high in the tree tops, but also flew over the herb vegetation of the road verges where it vistited flowers.
- UPDATE: since 2011 the species is observed yearly and its numbers seem to increase every year. It strongly expended into the entire Liesjärvi area!
