Coleophora arctostaphyli is a moth of the Coleophoridae family. It is found from Fennoscandia to the Iberian Peninsula and Italy and from Great Britain to Poland. The wingspan is 12–14 mm. The larvae feed on Arctostaphylos uva-ursi. They create a spatulate leaf case of about 8 mm long. The mouth angle is about 45°. Before making its first case, the young larvae live in a frass-filled contorted corridor. The larval stage lasts two seasons. In the first autumn, they live in a mine, where hibernation occurs. After hibernation, a case is made in which it feeds until spring, then aestivates, feeds in autumn and overwinters for the second time. During the second spring, a new case is made and the larva feeds until April or May when it is full-grown.
