Peacock (Inachis io)

.... and in Manx that's Peacag

Passport crop

A large, striking butterfly, with deep red wings and large distinctive eye spots from which it gets its name. Its life history is similar to the Small Tortoiseshell - it is at its commonest in gardens during late July and August, has the same caterpillar foodplant (stinging nettle), eggs are laid in large batches and the caterpillars are gregarious. Single brooded. Overwinters as an adult butterfly but unlike the Small Tortoiseshell rarely uses outbuildings to do so and instead prefers hollow trees or woodpiles.

The Peacock has undergone a resurgence in numbers in recent years. Very few Peacocks were recorded through the 1960's and 1970's.

On the wing from late March to mid June and then from late July through to late September, although many will have entered into hibernation well before the end of the flight period.
