Habitat & Geographic Range

Buckelwal

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cock's-head Bell

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Cock's-head Bell

The cock's head bell moth (Zeiraphera isertana) is a small tortrix moth in the family Tortricidae, occurring across deciduous and mixed woodland habitats in northern and central Europe, including Belgium, Denmark, Norway, and Sweden, as well as Britain and much of temperate continental Europe. Adults have a wingspan of approximately 16–22 millimetres and display intricate grey, brown, and white patterning on the forewings that provides effective cryptic camouflage against tree bark and lichens. The species flies in a single generation from July to September, and adults are nocturnal, coming to light. Larvae feed on the foliage of a range of deciduous trees, with oak (Quercus), hazel (Corylus), and related broadleaf species among the recorded host plants; larvae spin and bind leaves together as feeding shelters in a manner typical of many tortricid moths. Pupation occurs in leaf litter or bark crevices. Zeiraphera isertana is classified as Least Concern by the IUCN, reflecting its wide distribution and association with a broad range of common host tree species in well-established broadleaf woodland across its European range. The species belongs to a large genus that includes some economically important pests of conifers and orchards, though Z. isertana itself is not considered a significant pest. It is regularly recorded in standard moth surveys across Scandinavia and central Europe.
