Adult: grayish to grayish brown; the pattern is usually indistinct except for the prominent discal dot,with the subterminal area varying from being concolorous with the wing to light gray or orange (in early spring specimens), and with a faint darkened spot above the outer angle. The hind wings are concolorous with the forewings, and have a small discal spot and a variably represented extradiscal line. The under surface is basically similar to the upper, but with a greater degree of variation, as the maculation varies from faint to very prominent
Larva: Caterpillar very variable in color, but usually with a pattern of diagonal lines which commonly "join over dorsum to form arrows atop first six or seven abdominal segments." (4)
