Coleophora peri is a moth of the family Coleophoridae. It is found in Sweden.
The wingspan is 12–14 mm. Adults are on wing from the end of June to July.[1]
The larvae feed on Potentilla fruticosa. They first create a hairy, spatulate leaf case of about 7 mm. The mouth angle is about 30°. In spring, they bore into a developing bud, perforating the base of the scales, and eat them out. Later, they start mining again.[2] Larvae can be found from autumn to June.
