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 Green Capsid

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Widely distributed across Asia (Taiwan), 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 Green Capsid

<em>Lygocoris pabulinus</em>, commonly known as the common green capsid, is a plant bug belonging to the genus Lygocoris within the family Miridae. The species inhabits virtually all terrestrial and freshwater habitats, reflecting a generalist ecological strategy. Its documented range spans Taiwan in Asia, four European countries, and both Canada and the United States in North America. Common green capsid is assessed as Least Concern on the IUCN Red List. This small heteropteran is typically bright green in color and is associated with a wide variety of herbaceous and woody host plants, occasionally reaching pest status in agricultural settings where it damages soft plant tissue. Biological traits of this species remain poorly documented in the scientific literature.
