Coleophora pennella is a moth of the Coleophoridae family. It is found in most of Europe. The wingspan is 15–20 mm. Adults are on wing from June to July. The larvae feed on Anchusa officinalis, Cynoglossum officinale, Echium italicum, Echium vulgare, Lithospermum officinale, Myosotis, Nonea, Onosma, Pentaglottis, Pulmonaria officinalis and Symphytum officinale. Young larva feed on the developing seeds and hibernate in their first case which is made of the tip of a petal. After hibernation, they make a laterally flattened, composite leaf case. Fleck mines are made at the margin of the leaves. The mouth angle is about 70°. Full-grown larvae can be found from mid May to early June.
