Habitat & Geographic Range

Coastal Flat-body

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Common barley

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Africa (Sao Tome and Principe), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (4 countries).

Coastal Flat-body

Agonopterix yeatiana, the coastal flat-body, is a small moth in the family Depressariidae native to coastal and calcareous grassland habitats across western and northern Europe, with records from Belgium, Denmark, and Sweden. Moths in the family Depressariidae, commonly called flat-body moths due to the depressed posture they adopt when resting with wings held flat against the surface, are associated predominantly with umbellifer plants of the family Apiaceae as larval hosts. Agonopterix yeatiana larvae feed on wild carrot (Daucus carota), wild parsnip (Pastinaca sativa), and related coastal and grassland Apiaceae species, inhabiting the open, often calcareous or sandy habitats where these plants grow. Adult moths have greyish-brown forewing with a distinctive pattern of spots and dashes and reach approximately 8–12 millimeters in wingspan. The species is classified as Near Threatened by the IUCN, reflecting declines associated with the loss of traditional hay meadow management, coastal grassland degradation, and scrub encroachment that eliminates the open, flower-rich grassland habitats supporting its host plants. Agricultural intensification has reduced wild umbellifer populations significantly across lowland Europe, reducing food resources for larvae of specialist moths like A. yeatiana.

Common barley

Common barley (<em>Hordeum vulgare</em>) is one of the world's oldest and most widely cultivated cereal grasses, with a cosmopolitan distribution spanning Africa, Asia, Europe, North America, Oceania, and South America. It thrives in a diverse range of habitats including grasslands, wetlands, forests, and cultivated agricultural fields, demonstrating remarkable ecological adaptability. As a domesticated crop plant, <em>Hordeum vulgare</em> has been selectively bred for thousands of years and is now a staple grain used in food production, animal feed, and the brewing of beer and whisky. The plant typically grows as an annual grass, producing distinctive grain heads with elongated awns. It is particularly tolerant of cool, dry conditions, which has enabled its cultivation at higher altitudes and in regions where other cereals struggle. Barley is rich in dietary fiber, vitamins, and minerals, making it nutritionally significant. Its global distribution reflects both its natural range and extensive human-mediated dispersal. Biological traits of this species remain poorly documented in the scientific literature.
