Identification

This geographically variable, medium-sized butterfly is larger than most satyrs. It is about 1¼ long and has 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.

 
Similar
Species

Eyed brown (Lethe eurydice) forewing has 4 much smaller eyespots.

Northern pearly eye (Lethe anthedon) wing undersides have at least 2 dark, wavy lines. The forewing has 4 eyespots.


Larval Food

Grasses, including purpletop tridens (Tridens flavus var. flavus) and big bluestem (Andropogon gerardii).

 
Adult Food

Flower nectar, rotting fruit.

 
Life Cycle

Females lay single eggs on host grasses in late summer. Caterpillars hatch in the fall and overwinter. They begin feeding in the spring. Males emerge from late June to August, seldom feed, and last for about 2 weeks. Females emerge later and last for about 4 weeks.

Comments

Subspecies
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.

What’s in a Name?
The common name is a misnomer. This species is found in open areas or at the edges of woodlands.
