I obtained eggs from a worn ♀ taken at light near Salt Lake City, Utah, in June; these gave me a fine lot of imagines early in September, and I again got eggs from them, and had larvæ feeding which produced a number of moths at various times during the winter. Some of the larvæ ceased to feed when one-third grown, and I dumped them out among weeds by my orchard fence to take their chances.
