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.
