As adults they often fly low to the ground but can be seen flying up into trees where they will hang onto a twig below a leaf, mimicking a dead leaf with their wings closed. They will more often land on the ground. When disturbed they have a strong flight but usually do not fly far before again adopting a camouflage position. The colours and patterns of the underwing are highly variable. The females have slightly more rounded wings than the males. The hindwing extends into a short tail which can resemble the leaf stem when the butterfly is at rest.
This individual has overwintered here. I can be sure that it is the same one because of the slightly deformed wings easily visible below.
