Butterflies - Peacock (Aglais io)

The unmistakable Peacock, is one of The most beautiful and readily identifiable butterflies in The UK. The eyespots act as a highly effective deterrent to potential predators which even manage to frighten large birds away. The underside of the wings are almost black and render the butterfly almost invisible when its wings are folded upright. If that isn't enough, a loud grating noise produced by the rasping of The forewings also acts as a secondary deterrent

The territorial instinct of the male Peacock protecting a prime patch of nettles often results in males trying to chase off birds who venture too close to his patch.

Hibernation takes place in hollow trees, garden sheds and other sheltered places. Hibernating Adults can sometimes be seen on the wing in January on mild sunny days and is usually seen throughout late spring, summer and early autumn, with a peak in numbers in August.

Please note that the scientific (latin) name for the Peacock changed in 2011 from Inachis io to Aglais io.
