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 box

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Africa (Libya, Sao Tome and Principe), Asia (Armenia, India, Taiwan), Europe (15 countries), North America (United States), and South America (Colombia, Ecuador).

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 box

The common box (<em>Buxus sempervirens</em>) is a slow-growing evergreen shrub or small tree with one of the widest distributions of any species in its genus, occurring across Africa, Asia, Europe, North America, and South America. It typically inhabits diverse terrestrial ecosystems, from limestone hillsides and rocky slopes to woodland understories and cultivated gardens. The common box has not been formally evaluated on the IUCN Red List. Long valued in horticulture and topiary, this species is widely cultivated and naturalized far beyond its native range in southern Europe, western Asia, and northern Africa. Its dense, hard wood is among the heaviest produced by any European tree, historically used for woodworking and engraving. The species often forms dense thickets in natural settings, providing important shelter for invertebrates and small vertebrates. Biological traits of this species remain poorly documented in the scientific literature.
