Description
 
 

Common wood nymph is a geographically variable, medium-sized butterfly.

Adults are about 1¼ long, larger than most satyrs, and have a 1¾ to 3 wingspan. There is a light form, with light brown wings and body, and a dark form, with dark brown wings and body.

It perches with wings closed, so the upperside of the wings are rarely seen. The underside of the forewing is brown and has a 2 large, black, yellow-ringed eyespots with white pupils. Usually, just one of these spots is visible on a perched individual. Common wood nymph (C. p. pegala) has a yellow patch surrounding the eyespots. Dull-eyed grayling (C. p. nephele) does not. A single thin, dark, wavy line separates the darker forward portion of the wings from the usually somewhat paler rear portion.

The underside of the hindwing is brown with usually 6 similar but smaller eyespots.

Subordinate Taxa

 
 

At least 21 subspecies have been described based in some cases on subtle color variations. Populations in the eastern part of the species’ range often have individuals of two or more subspecies. This suggests that some of the differences may be color morphs as opposed to separate subspecies. Darkness may be an adaptation within a population or an individual to the amount of direct sunlight to which it is exposed.
