Morley's Final Catalogue: Extinct; its last British home was in Suffolk. First described from Kentish specimens in 1775 (cf also Substitute 1857, p.159); Stowmarket (Shield's Hints 1855, 78; Ent. Ann. 47, &c.); Scotland (Stn. Manual 1856, &c); Creeting near Needham in 1865 (EMM. 1866, 208). Barham about 1867 (Bloomfield 1890, 29), and Ipswich (Ent. 1868, 331). Essex in 1867 (Ent. Ann. 119). Barrett's Devon and Meyrick's Norfolk records are erroneous, as also is King's (Naturalist 1858, 61) from Raydon. The final specimens were captured 'near Stowmarket' by Mr. Percy C. Reid in 1911 (Gilles, in lit. Jan. 1933; cf. EMM. lxix, 32). Probably a salt-estuarine species, like Leptomeris rubiginata above.

Recent Suffolk Status: Extinct.

Life history: Was double-brooded. Flew in the daytime and was readily disturbed from the foodplant.

Identification: None.

Habitat: Formerly Broom stands in sunny situations such as railway enbankments.
