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.

Common Fruit-tree Pigmy

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.

Common Fruit-tree Pigmy

<em>Stigmella oxyacanthella</em>, commonly known as the common fruit-tree pigmy, is a small moth in the family Nepticulidae. This species has been documented in Belgium, Denmark, Norway, and Sweden, and its range is understood to extend more broadly across parts of Europe. Nepticulidae moths are among the smallest Lepidoptera, and species in this family are typically leaf miners, with larvae feeding within the leaf tissue of host plants. <em>Stigmella oxyacanthella</em> is associated with woody plants in the rose family (Rosaceae), with its common name reflecting an association with fruit trees and hawthorn. The species is assessed as Least Concern, consistent with its distribution across multiple northern European countries. As a leaf-mining species, it contributes to insect diversity within deciduous woodland and orchard habitats. Biological traits of this species remain poorly documented in the scientific literature. The adults are characteristically tiny, with narrow wings and long antennae, and are most readily identified through the distinctive leaf mines produced by their larvae rather than by direct observation of the adult moths.
