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 Grape Hyacinth

Habitat

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

Range

Widely distributed across Asia (Japan), Europe (14 countries), and North America (Canada, United States).

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 Grape Hyacinth

<em>Muscari botryoides</em>, commonly known as common grape hyacinth, is a bulbous flowering plant belonging to the genus Muscari within the family Asparagaceae. The species inhabits grasslands, wetlands, forests, and cultivated landscapes, demonstrating considerable versatility across managed and natural environments. Its native and naturalized range includes Japan in Asia, fourteen European countries, and populations in both Canada and the United States in North America. Common grape hyacinth is assessed as Least Concern on the IUCN Red List. The species typically produces dense racemes of small, urn-shaped blue to violet flowers in early spring, making it a recognizable element of both wild and garden landscapes across its range. Biological traits of this species remain poorly documented in the scientific literature.
