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.

Cocoa moth

Habitat

Found across multiple habitat types including tropical and subtropical dry broadleaf forests, deserts and xeric shrublands, and Mediterranean forests and woodlands spanning the Afrotropic and Palearctic realms.

Range

Widely distributed across Africa (Cabo Verde), Asia (4 countries), Europe (30 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.

Cocoa moth

The cocoa moth (Ephestia elutella) is a small moth in the family Pyralidae with a wingspan of 14–22 millimetres, cosmopolitan in distribution as a stored-product pest. The species is native to Europe but has spread globally through trade in stored commodities, particularly cocoa beans (from which its common name derives), dried fruits, tobacco, grain, nuts, and confectionery. Adults are greyish-brown with subtle patterning on the forewings; they are short-lived and do not feed as adults. Females lay eggs directly in or near food material; larvae are creamy-white with dark head capsules and spin silken webbing through infested commodities as they feed, causing significant post-harvest economic losses. Like other pyralid stored-product moths, E. elutella is a major pest of food processing and warehousing facilities worldwide, thriving in warm, dry storage conditions with high carbohydrate content. It has been recorded from at least 30 European countries and is present on all inhabited continents. Control relies on temperature treatment, pheromone-baited monitoring traps, and chemical insecticides, though resistance to some compounds has been reported. The species is classified as Least Concern by the IUCN, reflecting its global distribution and thriving populations in human-modified environments. Its economic importance has made it the subject of extensive research into stored-product pest biology, chemical ecology, and integrated pest management strategies.
