63 - 69mm
A large butterfly with an overall colour of reddish-brown velvet distinguished by a large purple-blue roundel or 'eye' in the frontal outermost quarter of each wing (four in total) - the rear being more prominent than those on the fore-wing. This is a device for warning off predators.
The adult Peacock butterfly emerges in late July and August and is seen flying through September, but can be seen entering buildings to hibernate as soon as the temperature starts to drop.
The Peacock is one of the most 'domesticated' of our butterflies and appears frequently in gardens and parks where its favourite nectaring plant, the flowers of Buddleia davidii, or Butterfly Bush, are abundant. It also nectars on clover and other tall flowering plants such as thistles. It has a preference for purple flowers, and is also attracted to rotting fruit in orchards.
