Morley's Final Catalogue: This splendid noctuid, expanding 100 mm. i.e. nearly four inches, is regarded as indigenous. At least a round dozen examples have been captured in Suffolk during the past century. The first appeared 'near Lowestoft in September 1828 to G. Waterhouse' (Stph. Illust. iii, 1830, 132). Two were met with at Clare, and one at Whixoe near that town, in 1868 (E.A. Fitch), a remarkable season wherein a fifth was taken on sugar at Aldeburgh on 21 August (Wrt, Suf. Inst. 4ly Journ., Jan. 1869, 23; Proc. iv, 1870, 220), along with an undated sixth that year (Hele, Aldeb. 190), in the course of which Balding found a seventh (EMM. v. 128) and Miller eighth both in August at Ipswich, as well as two more there in 1872 - Miller's records from Bramford and Lowestoft (Lep. Suff. 1890, 25) are erroneous, teste Bloomfield. Not till 1901 occurred our eleventh specimen, sitting upon a house called Stronsay at Kirkley Cliff in Lowestoft (EMM. 1904, 256: two specimens exist in Dr. Hutchinson's Lowestoft collection). A perfect specimen came to sugar in the grounds of Benacre Hall on 24 August 1901 (J.F. Green, Ent. Rec. 1901, 306; cf. his paper on 'Mothing in Suffolk,' Knowledge 1901, pp. 231-1); and South gives one in 1905.
Recent status: Certainly breeding in the county now.
