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 Lilac

Habitat

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

Range

Widely distributed across Africa (Libya), Asia (4 countries), Europe (29 countries), North America (Canada, United States), and Oceania and the Pacific (Australia).

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 Lilac

<em>Syringa vulgaris</em>, the common lilac, is a deciduous flowering shrub or small tree in the family Oleaceae, native to the Balkan Peninsula of southeastern Europe. It has been widely cultivated and naturalized across Africa, Asia, Europe, North America, and Oceania, making it one of the most globally distributed ornamental shrubs. The common lilac typically grows in temperate climates, preferring well-drained soils and full sun exposure. It is renowned for its dense, fragrant flower panicles, which range from pale lavender to deep purple and appear in spring. The species has not been evaluated for its conservation status by the IUCN, reflecting its widespread cultivation and lack of known population threats. Common lilac is extensively used in horticulture and perfumery, with hundreds of cultivated varieties developed over centuries. Its flowers are a valuable nectar source for pollinators including butterflies and bees. The species typically blooms in late spring and can live for many decades in suitable growing conditions.
