Recent Activities

July 2018 the weather was extremely warm. The water of lake Liesjärvi even reached a temperature of 28 degrees Celsius! This summer I managed to visit some nearby water bodies that were not yet visited for dragonfly excuvia.

I could record a new dragonfly and butterfly species for the area. I observed an adult of the dragonfly species Pohjanukonkorento (Aeshna caerulea) and also found one excuvia of this species. The new butterfly species is in fact a sub-species of Ketohopeatäpla (Argynnis adippe). During the last 15 years I have observed many A. adippe, but this was the first sighting of an A. adippe forma cleodoxa.
