Polen, Woiwodschaft Podlachien, Zabludow, 153 m, 2. August 2015 (Freilandfoto: Marek Idec)
I have some butterflies photos I took myself and I'd like to identify them all. Some of them are obvious, but some others not and I'm going to send them to this forum asking for your help.
Regarding these two photos, I have doubts about whether it's really Colias erate as Colias hyale seems very similar.
If you can figure this out I'd like to know what detail actually made you thinking that this is C. erate or C. hyale.
Thanks in advance. Best regards,
