Coleophora flavipennella

Coleophora flavipennella is a moth of the family Coleophoridae. It was described by Philogène Auguste Joseph Duponchel in 1843 and is found in Europe.

C. flavipennella's life cycle begins with the egg stage, when eggs are placed on host plants. Upon hatching, the larvae construct protective cases around themselves using silk and fragments of plant material. The larval stage of C. flavipennella is the longest phase of its life cycle, lasting several weeks to months, depending on environmental conditions and host plant availability. Once completely developed, the larvae pupate within their casings and undergo metamorphosis before emerging as adult moths.

The wingspan is 11 –.

The larvae feed on sweet chestnut (Castanea sativa), sessile oak (Quercus petraea), pedunculate oak (Quercus robur) and northern red oak (Quercus rubra). Full-grown larvae can be found in May.
