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 Marbled Carpet

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (4 countries) and North America (Canada, United States).

Common corncockle

<em>Agrostemma githago</em>, 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 Marbled Carpet

<em>Dysstroma truncata</em>, the common marbled carpet, is a geometrid moth in the family Geometridae distributed across Europe and North America. It is classified as Least Concern on the IUCN Red List, reflecting stable populations across its wide temperate range. The species is typically found in woodland, hedgerow, and garden habitats where its larval food plants are present. Its wings display complex, marbled patterns in shades of brown, grey, and white, providing effective camouflage against tree bark and leaf litter. Adults are typically nocturnal and are recorded from spring through autumn, with multiple generations possible in warmer parts of its range. Larvae feed on a variety of deciduous plants including bilberry, heather, and various shrubs. The common marbled carpet is a familiar species to moth recorders across temperate Europe and North America, where it is frequently encountered at light traps. Its widespread distribution and habitat generalism contribute to its secure conservation status across both continents.
