It is often wintering in buildings or trees. It therefore appears quite early in spring. The peacock butterfly has figured in research in which the role of eyespots as an anti-predator mechanism has been investigated.

The recorded food plants of the larvae are stinging nettle (Urtica dioica), hop (Humulus lupulus), and the small nettle (Urtica urens).
