Peacock Aglais io

    Formerly Inachis io

 

 

Unlike the Small Tortoiseshell, Peacocks have only a single generation each year, the adults living from late July or August round to April or May, though they may be found flying in warm weather in any month of the yearThey hibernate indoors as well as in woodlands, the dark undersides of both these species and the Comma serving to camouflage them from predators, though even so many are killed by mice and birds. .
