Peacock (Inachis io (Linnaeus, 1758))

Scientific name: Inachis io (Linnaeus, 1758)
Common name: Peacock
French name: Paon du jour
Order: Lepidoptera
Suborder: Rhopalocera
Family: Nymphalidae
Subfamily: Nymphalinae
Wingspan: 54-60 mm
Biotope: Widespread in many habitats.
Geographic area: Europe except North of Scandinavia and North of Scotland. Temperate Asia.
Flight time: July to October.
Number of generations : 1
Caterpillar: Shiny black, hairy with white spots.
Host plant: Nettles (groups of caterpillars) and sometimes hops.

The bright red upper side of the wing, with a clear eye pattern, contrasts with the black brownish underside. This dark underside colour provides a good camouflage while resting and during winter.
The eye patterns are exposed to frighten any eventual predator.
Both sexes are similar.
The Peacock flies from the middle of Summer to the first cold days. Then it appears again at the beginning of Spring after having wintered in a tree or a building.

Peacocks are regular visitors of the Buddleia flowers in my garden. Here is my best picture at this time.

Light is beautiful at the end of this afternoon of June. A Peacock, landed on the ground, flies away as I come near.
I stop at a small distance and it lands exactly at the same place.
I walk closer with my camera, it flies away, I walk the other way, it lands again at the same place. I must find something to take this picture.
Nobody in the area… I get closer, but crawling on the ground, in the direction of the backside of the butterfly.
This works! I am even able to have the camera, less than 30cm, on top of the Peacock.

Peacocks enjoy resting in the sun light. We can even take pictures of the underside.

The dark colour of the underside of the Peacock's wings really contrasts with the bright colours of the upper side.
I had difficulties to get a correct exposure. I think that the best way is to use exposure memorization pointing to a paler thing (leaf, trunk, etc.).

I have observed this caterpillar in a clearing.
There were some pieces of black caterpillar skin on the Nettles in the vicinity. Are these dead caterpillars or are these remains after molting?

Some Peacocks sometimes winter hanging upside down on the ceiling of my garage.
They fly out on the first hot days of the next Spring.
