Coastal Brown

Cassionympha perissinottoi, the coastal brown, is a butterfly in the family Nymphalidae, subfamily Satyrinae, endemic to the coastal regions of South Africa. Satyrines, commonly called browns or ringlets, are typically medium-sized butterflies with cryptic brown and orange wing patterns that blend effectively with grass and dead vegetation in their grassland and woodland edge habitats. Cassionympha perissinottoi inhabits coastal grassland, dune thicket margins, and moist grassy areas along the eastern South African coast where suitable grass species, which serve as larval host plants, are available. The genus Cassionympha is endemic to Africa and comprises a small number of related species adapted to grassland and savanna habitats. Like many satyrid butterflies, the larvae feed on grasses and the adults feed on rotting fruit, dung, or take moisture from wet soil rather than flower nectar. The species is classified as Least Concern by the IUCN, though coastal grassland habitats in South Africa have been significantly reduced through urban development, plantation forestry with invasive pines and eucalypts, and coastal resort development along the KwaZulu-Natal shoreline.
