Habitat & Geographic Range

Common corncockle

Habitat

Found across multiple habitat types including montane grasslands and shrublands, tropical and subtropical moist broadleaf forests, and temperate coniferous forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Glider

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (19 countries).

Common corncockle

Agrostemma githago, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.

Common Glider

Neptis sappho, commonly known as the common glider, is a butterfly in the family Nymphalidae. The species has a broad European distribution, with documented occurrences in 19 countries across the continent. Neptis sappho typically inhabits woodland edges, clearings, and scrubby areas where its larval host plants, primarily species of legumes such as Lathyrus and Vicia, are available. The species is assessed as Least Concern, reflecting its reasonably wide distribution across temperate and sub-Mediterranean Europe. The common glider is named for its characteristic flight pattern, which involves alternating periods of gliding and flapping, producing a distinctive sailing motion through woodland habitats. Its wings are dark brown with white bands and spots that create a striking pattern visible during flight. Biological traits of this species remain poorly documented in the scientific literature. The species typically produces one or two generations per year depending on latitude and climate, and adults are often observed nectaring at flowers in sunny woodland clearings and along forest margins.
