Coast Conch

Coast conch (Gynnidomorpha permixtana) is a small moth in the family Tortricidae, subfamily Tortricinae, native to coastal habitats of northwestern Europe, including the United Kingdom, France, the Netherlands, and Scandinavia. Adults are small, with a forewing pattern of pale ochre and grey typical of many tortricid moths. Like other members of the genus Gynnidomorpha, the larvae are thought to feed on low-growing coastal plants. The species is associated with open, vegetated coastal habitats such as sand dunes, vegetated shingle, and coastal grasslands. Despite the common name referencing a 'conch', this is a tortrix moth—the name 'coast conch' follows a vernacular naming convention used for British moths in which 'conch' designates tortrix species. It is assessed as Least Concern by the IUCN, consistent with its wide distribution across northwestern European coastal habitats. Like many coastal invertebrates, it may be locally affected by dune stabilisation, scrub encroachment, and recreational pressure on coastal habitat, but no evidence of major population decline has been documented at a species level.
