Ceranemota crumbi is a moth in the Drepanidae family. It was described by Benjamin in 1938. It is found in North America, where it has been recorded from western Oregon and the Washington Cascade Range. The habitat consists of coastal rainforests and mixed hardwood forests. The length of the forewings is 14–17 mm. The forewings are brassy brown-grey, but lighter grey in the terminal area. The hindwings are dark brown-grey with faint darker markings. Adults are on wing from late October to late November in one generation per year. The larvae probably feed on hardwood species.
