Polen, Woiwodschaft Großpolen, Pila (Schneidemühl), mein Garten, 60 m, 1. October 2017 (Freilandfoto: Marek Idec)
I have big trouble with this butterfly. I searched it in books and on the internet and it seems to be closest to Erebia pharte. According to the sources Erebia pharte flies in July and in August but I took these pictures on the 1st of October. Any idea what it could be?
If I'm not mistaken I photographed the butterfly on a grape leaf. Maybe it's not Erebia at all? Thanks for help.
