Female forewing is gray-brown and has a black line outlining a darker basal area.
Hindwing is slightly paler and may have pink at the base or along the inner margin. Each wing of both male and female has a faint black submedian line and a small black eyespot. Shortly after mating, females lay eggs in clusters of 5-12 at the base of pine needles. Eggs hatch in about three weeks. Young caterpillars are gregarious, with 3-5 caterpillars feeding together on the same pine needle.
