Coast Dart

Coast dart (Euxoa cursoria) is a medium-sized moth in the family Noctuidae, native to coastal sand dunes and sandy heathland habitats of northern and western Europe, including the United Kingdom, Denmark, the Netherlands, Germany, and Scandinavia. Adults are cryptically patterned in pale buff, grey, and brown tones that match the sandy substrates of their dune habitat, flying at night from late summer into autumn. Larvae feed on the roots of coastal dune grasses and other low-growing plants, overwintering as pupae in loose sand. The genus Euxoa includes numerous 'dart' moths distributed across the northern hemisphere, many of which are habitat specialists tied to open, sandy ground. Coast dart populations have declined significantly across their European range due to the stabilisation and vegetational succession of coastal sand dunes, reduction of bare sand patches through marram grass planting, and recreational disturbance. Despite these pressures, it is assessed as Least Concern by the IUCN. In the United Kingdom, it is classified as a priority species in the Biodiversity Action Plan and is the subject of dune management programmes aimed at maintaining open sand habitat.
