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 Hooktail

<em>Paragomphus genei</em>, commonly known as the common hooktail, is a dragonfly in the family Gomphidae. It is classified as Least Concern on the IUCN Red List, suggesting a stable and widespread population. The species is noted to occupy virtually all terrestrial and freshwater habitats within its range, reflecting considerable ecological generalism typical of many gomphid dragonflies. Specific country-level distribution records for this species are not detailed in current data, though the breadth of habitat use implies a relatively wide geographic range across suitable regions. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
