The Grey Hadena caesia

([Denis & Schiffermüller], 1775)

---

Wingspan 36-42 mm.

A very local species, occurring in a small number of western coastal localities, notably in the Western Isles, Isle of Man and south-west Ireland.

It frequents rocky seaside habitats close to the shore, usually within a short distance from the shoreline.

The larvae feed on sea campion (Silene maritima), and the adults fly between May and August.
