Habitat & Geographic Range

Common Kidney-Vetch

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, among 6 distinct biome types spanning the Indomalayan and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya), Asia (Japan), Europe (9 countries), North America (Canada, United States), and Oceania and the Pacific (Australia). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Kidney-Vetch

Common Kidney-Vetch (<em>Anthyllis vulneraria</em>) is a flowering plant in the legume family Fabaceae, assessed as Vulnerable on the IUCN Red List due to habitat degradation and agricultural intensification across parts of its range. It is widely distributed across Africa (Libya), Asia (Japan), Europe (nine countries), North America (Canada and the United States), and Oceania (Australia), occupying six distinct biome types and occurring within the Indomalayan and Oceanian biogeographic realms. The species typically grows in dry, calcareous grasslands, coastal cliffs, sand dunes, and rocky slopes, often favoring nutrient-poor soils. It is an important larval food plant for certain butterfly species, particularly the Small Blue butterfly in Europe, and contributes to soil fertility through nitrogen fixation via root nodules. Its cheerful yellow, orange, or red flower heads make it a recognizable component of chalk and limestone grassland communities. Biological traits of this species remain poorly documented in the scientific literature.

common swift

<em>Korscheltellus lupulina</em>, the common swift moth or ghost swift, is a moth in the family Hepialidae, order Lepidoptera. It is recorded from Belgium, Denmark, Norway, and Sweden, with a broader distribution across Europe and temperate Asia. The species typically inhabits grasslands, meadows, garden lawns, and field margins where its larval host plants grow. Adult ghost swifts are notable for their spectacular lek-like swarming behavior at dusk, in which males hover in groups to attract females, appearing to hover like ghosts over vegetation. Larvae of <em>Korscheltellus lupulina</em> feed underground on the roots of a variety of herbaceous plants and grasses, including hop (Humulus lupulus), which gives the species its specific name. Adults do not feed, having vestigial mouthparts, and live only long enough to reproduce. Biological traits including precise larval duration, adult size measurements, and detailed host plant specificity remain poorly documented at the species level. The species is assessed as Least Concern by the IUCN, with stable populations across its European range and no significant conservation threats identified.
