Reference to Birch, at least in Britain, stem from confusion with C. milvipennis (Emmet ao, 1996a). However, mentioned explicitly from Birch by Baldizzone ao (2004a).


Larvae begin in September, feed till end October, making two youth cases in this period, then go into hibernation. They resume feeding in May and make their final case, in which they pupate around June.In Britain, but probably not on the Continent, the larva often hibernates a second time (Emmet ao, 1996a).
