Aglais io (Linnaeus, 1758)



A medium sized butterfly. The underside is a dark marbled colour with no obvious markings. The upperside is very distinctive, being  maroon with what look like two large “eyes”, one of each wing. If resting with its wings closed, the butterfly will flash these “eyes” if disturbed so as to deter or distract any potential predator. Males and females are similar.

Habitat Requirements

We know very little about the existance of this species in Corfu. Its possible that it is a local resident in the north eastern corner of the island.

Larval Foodplants

Nettle Urtica dioica, Hop Humulus lupulus, Eastern Pellitory-of-the-wall Parietaria officinalis.


Only the one sighting of this species has been made by CBC member David Cook. David recorded the butterfly on Mt Pantokrator 31 May 2019. Presumably a hill topping migrant.
