Common oak case-bearer

<em>Coleophora lutipennella</em>, the common oak case-bearer, is a small moth in the family Coleophoridae. The larvae of this species construct characteristic portable cases from plant material and their own silk, from which they feed on the leaves of their host plant. <em>Coleophora lutipennella</em> is associated with oak trees (Quercus species), which serve as the primary larval host, and the moth typically inhabits deciduous woodland, forest edges, and hedgerows where oaks are present. Its geographic range spans temperate Europe, with documented occurrences in Belgium, Denmark, Norway, and Sweden. The species is currently assessed as Least Concern by the IUCN. Biological traits such as lifespan, body size, and diet remain poorly documented at a formal population level for this species, though larval feeding on oak foliage is well established. Adults are small and inconspicuous, typically flying in summer. <em>Coleophora lutipennella</em> is part of a diverse guild of Lepidoptera associated with European oak woodland ecosystems, and contributes to the invertebrate prey base for insectivorous birds and other woodland predators.
