Habitat & Geographic Range

Blauwal

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 (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.

Zweizahn-Winkelspanner

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Blauwal

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Zweizahn-Winkelspanner

The cloaked carpet (Euphyia unangulata) is a geometrid moth in the family Geometridae found across temperate Europe and parts of western Asia. The adult wingspan typically measures 22–28 mm, with forewings displaying the characteristic carpet moth pattern of transverse bands and cross-lines in shades of grey, brown, and white, providing effective camouflage against tree bark and lichen-covered surfaces. The species inhabits deciduous woodland, scrubby hedgerows, and woodland margins where its larval foodplants, including chickweed (Stellaria species) and related low-growing herbaceous plants, are abundant. Adults fly in one or two generations per year depending on latitude, typically on the wing from late spring through late summer. Larvae feed through summer and autumn, pupating in soil or leaf litter. Like many geometrid moths, the cloaked carpet has experienced population declines across parts of its European range, attributed to loss of diverse woodland understory, reduction in traditional coppicing practices, and changes in land management that reduce the availability of shaded, moist microhabitats where foodplants thrive.
