Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Birch Bell

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

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.
