Range

Distributed across Denmark, Norway, and Sweden. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its 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.

Cliostomum corrugatum is a crustose lichen in the family Ramalinaceae, notable for producing characteristically wrinkled or corrugated apothecia that distinguish it from related taxa. The genus Cliostomum is a small group of saxicolous and corticolous crustose lichens with a disjunct distribution in temperate and boreal regions of the Northern Hemisphere, including Europe and North America. The thallus of Cliostomum corrugatum is thin and pale, often nearly immersed in the bark substrate on which it grows, while the pale tan to cream apothecia are flat to slightly convex with the distinctive corrugated or rugose surface. The species is found on the bark of deciduous trees in old, undisturbed woodland, including veteran oaks, beeches, and other broadleaved trees with stable, relatively unpolluted bark chemistry. Cliostomum species are considered indicators of ecological continuity in woodland habitats and are included in lists of ancient woodland indicator species in northwestern Europe. The species is sensitive to air pollution, particularly sulfur dioxide and nitrogen compounds from agricultural and industrial sources, and declined significantly across industrialized regions of Britain and Europe during the 20th century. Recovery has been noted in areas where air quality has improved. The species is of conservation concern in several European 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.
