October or early in November, but occasionally this latter 

 change does not take place until spring. 



The male moths have large and delicate wings (see Fig. 

 108) and feathered antennae. The fore wings, which measure, 

 when expanded, about an inch and a half across, are of a 

 rusty-buif color, sprinkled with brownish dots, and with two 

 transverse wavy brown lines, the inner one often indistinct, 

 while between the bands and near the edge of the wing there 

 is generally a brown dot. The hind wings are paler, with a 

 small brownish dot in the middle ; the body is similar in color 

 to the fore wings.
