Wood white

Wood white - Leptidea sinapis
It was quite an action to capture this otherwise ordinary butterfly. She (or he) kept flying without landing and this made me more willing to shoot her. Backpack, the other camera, tripod - they all left somewhere on the ground, I slipped in a gully following her, hardly managed to crawl back uphill after that, but finally she landed upside down for a couple of seconds. Two shots, and that's all!
