General Description

A medium-size (2.8-3.8 cm wingspan) grey-brown or brown moth with short bipectinate antennae and a characteristic tuft on the tip of the abdomen in males. The forewing is crossed by four fine pale lines, much more prominent in spring than in summer specimens. The apical quarter of the wing is dark chocolate or red-brown, sharply delineated from the remainder of the wing and separated at the costa by a short curved white bar. It can be separated from other Clostera species by the sharp demarcation of the dark apical patch on the forewing. It most closely resembles the smaller and darker Clostera brucei, which lacks the sharp contrasting separation of the dark apical area from the rest of the forewing. Spring specimens which are paler and marrked be a series of pale lines have been named form specifica; summer specimens are darker and more uniform in color and pattern. Sexes are similar, but female antennae are simple. See also Clostera apicalis.
