Coast Groundling

Coast groundling (Caryocolum vicinella) is a small moth in the family Gelechiidae, native to coastal sand dunes and sandy coastal habitats of northwestern Europe, including the United Kingdom, France, the Netherlands, Belgium, and Scandinavia. Like other members of the large and taxonomically complex genus Caryocolum, the larvae are leaf miners or feeders on specific plant hosts in the pink family (Caryophyllaceae), often specialising on coastal species such as sea campion (Silene uniflora) or related plants in coastal dune systems. Adults are small, narrow-winged moths with pale ochre, brown, or grey patterning, flying at dusk and nocturally in summer. The species is associated with open, mobile or semi-stabilised coastal dunes with abundant larval host plants. Coast groundling is assessed as Least Concern by the IUCN. However, like many gelechiid moths restricted to coastal dune habitats, it may be sensitive to habitat changes caused by dune stabilisation, scrub encroachment, and reduced management of sand dune systems. Long-term population trends are difficult to assess given the cryptic nature of the species.

Collembola

<em>Folsomides angularis</em>, commonly referred to as Collembola in reference to its broader taxonomic order, is a springtail species belonging to the genus <em>Folsomides</em>. Springtails are among the most abundant hexapods in terrestrial ecosystems, playing important roles in soil decomposition and nutrient cycling. This species has been documented in Europe, with records from Denmark, Norway, and Sweden, as well as North America, where it is known from the United States. It typically inhabits soil, leaf litter, and decaying organic matter, and is capable of tolerating a range of environmental conditions. Springtails of this group are detritivores, feeding on decomposing plant material, fungal hyphae, and microorganisms, though specific dietary data for <em>Folsomides angularis</em> are not detailed in current records. The species has not been formally assessed for conservation status. Biological traits of this species remain poorly documented in the scientific literature. Its small body size and cryptic lifestyle make detailed ecological study challenging.
