Soaring with powerful, rapid flights through the boreal and temperate forests of the Northern Hemisphere, Nymphalis vaualbum, commonly known as the Compton Tortoiseshell, is a striking and often elusive butterfly. Renowned for its jagged wing margins, mottled camouflage, and its unique life cycle that involves both summer aestivation and winter hibernation, this species is a fascinating example of adaptation to fluctuating seasonal conditions.
