Morley's Final Catalogue: Among the rarest of our heath moths, apparently. Confined to the wild tracts (1) to the east of Ipswich, where Tim Last used to take a deep-red form (Harwood) about 1880, including Rushmere Heath on which a single specimen occurred at sugared rags on 24 August 1895 (Mly) and (2) the Breck, where Wheeler of Norwich once found it rarely.

Recent Suffolk Status: Very rare. The last county record was in the Breck in 2004. Extinct in east Suffolk.

Life history: Single-brooded.

Identification: Dotted clay has the obvious black spot in the corner of the forewing. Square-spot rustic is superficially similar but the kidney mark is normally paler than the ground colour and square-shaped. Neglected rustic is larger than Sqare-spot rustic.

Habitat: Heathland.
