In 2019, I visited Liesjärvi in spring and summertime. I observed a total of 38 butterfly species of which 33 were seen in summer. This is the highest number since the last 16 years. Aricia artaxerxes (Lehtosinisiipi) and Perarge aegeria (Täpläpapurikko) were found for the first time.
It appeared to be a very good year for Sympetrum albifrons and S. caudalis, 34 and 28 excuvia, respectively, and many adult males present in several lakes. For the first time I found an excuvia of Sympetrum danae.
