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.

Clouded slender

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (6 countries).

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.

Clouded slender

Clouded slender refers to a small moth in one of several microlepidopteran families characterized by narrow, elongated wings with clouded or mottled patterning, the 'slender' designation reflecting the elongated wing shape typical of gracillariid leaf miners, stathmopodid moths, or similar narrow-winged families. Slender moths of this type are often highly specialized as leaf miners or stem borers in their larval stage, with adults emerging in spring or summer from pupae formed within the mined leaf or on adjacent vegetation. The clouded wing pattern typically consists of subtle brown, grey, and cream mottling or diffuse cross-banding that provides camouflage against bark and foliage substrates. Many slender moth species in Europe and Asia have restricted distributions tied to the availability of specific larval host plants, making them sensitive to changes in plant community composition. Documentation of species through light trapping and larval rearing from identified host plants contributes to understanding the full diversity of microlepidoptera in temperate and subtropical habitats where hundreds of species remain incompletely studied.
