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 pricklypear

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and deserts and xeric shrublands, among 9 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (15 countries), Asia (10 countries), Europe (7 countries), North America (Nicaragua, Panama, United States), Oceania and the Pacific (9 countries), and South America (Brazil, Venezuela).

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 pricklypear

The Common Pricklypear, <em>Opuntia monacantha</em>, is a cactus in the family Cactaceae with a remarkably broad global distribution, naturalized across Africa, Asia, Europe, and throughout the Americas and Oceania. Native to South America, it has been introduced widely and is considered invasive in parts of its non-native range. The species is characterized by its flat, oval to elongated green cladodes bearing sparse but long spines and dense glochids at each areole. <em>Opuntia monacantha</em> typically grows in dry, disturbed habitats including coastal areas, roadsides, agricultural margins, and degraded scrublands, thriving in full sun and well-drained soils. It produces yellow flowers and small purplish-red fruits that are consumed by birds and mammals, facilitating seed dispersal across its wide range. The plant utilizes CAM photosynthesis, allowing it to minimize water loss in arid conditions. In some regions, the species is cultivated for its edible fruits and as a livestock fodder. It is assessed as Least Concern on the IUCN Red List given its abundance and broad distribution. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
