Marbled Coronet Hadena confusa
Wingspan 33-39 mm.
Locally widespread over a large part of the British Isles, the species varies from a very black-and-white form to an almost all brown variety, occurring in Shetland.
The adults fly in May and June, sometimes with a partial second generation in the south-east of England.
Preferring chalky soils and shingle beaches, the larvae feed on the seeds of bladder-campion (Silene vulgaris), sea-campion (S. maritima) and other Silene species.
