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 stork's bill

<em>Erodium ciconium</em>, the common stork's-bill, is an annual or biennial flowering plant in the family Geraniaceae, order Geraniales. It is native to the Mediterranean region and southern Europe and has been introduced to parts of North America. The species typically inhabits dry, disturbed habitats including roadsides, cultivated fields, rocky slopes, and coastal areas, favoring sandy or calcareous soils with good drainage. Its pink to purple flowers are relatively small, and the distinctive elongated fruit resembles a stork's bill, a characteristic shared across the genus <em>Erodium</em>. The beak-like fruits are adapted for wind and animal dispersal, with hygroscopic awns that drill the seed into the soil through coiling movements in response to moisture changes. Biological traits such as typical lifespan duration, average biomass, and detailed dietary associations remain poorly documented at the species level. <em>Erodium ciconium</em> has not been formally evaluated by the IUCN, though it is generally considered a common species without significant conservation concern across most of its range.
