Common Birch Bell

The common birch bell (<em>Epinotia immundana</em>) is a small tortricid moth found in terrestrial and freshwater habitats across temperate Europe. Its confirmed range includes Belgium, Denmark, Norway, and Sweden. The species is classified as Least Concern on the IUCN Red List. As the common name suggests, <em>Epinotia immundana</em> is closely associated with birch trees, where its larvae typically feed on birch foliage and developing buds. The adult moths are small and cryptically patterned, making them difficult to detect at rest on bark or leaf litter. Like other members of the family Tortricidae, the larvae often roll or tie leaves together to create protective shelters during feeding. The species typically completes one or more generations per year, depending on local climate conditions. Biological traits of this species remain poorly documented in the scientific literature.
