A common species throughout Belgium.
The species hibernates in the adult stage. When disturbed during hibernation, they flap their wings revealing the brightly coloured top. They hope that this will scare off any enemies. Also, they can make a hissing noise with their wings, which would be even more terrifying.
The adults fly in two generation a year: from mid March till early June, and from early July till mid October.
The larva lives on Urtica dioica.
