Morley's Final Catalogue : This local moth, which extends no further north than Norfolk, was among the plums of the old Ipswich dealers, who failed to exstirpate it. Our earliest records are from Stowmarket (Ent.Wk. Intell. ii, 1857, 115) and Woolverstone by Dr. Bree (l.c. v, 1858, 30) ; next it was found at Aldeburgh (Hele 1870, 188), where Wratislaw discovered it 'in considerable quantity' (Suff. Inst. iv, 1870, 220). Before 1890, it had been further noted at Bixley decoy, Brandeston, Needham, Bury, Brandon and at Beccles. Later records show it at Copdock in 1896 (Hkg) ; at sugar (Ml) and rest in Ipswich (Baylis); single specimens in most years at Waldringfield (Wlr); near Bury and at Tuddenham St. Martin (Sparke); a few pupae annually before 1911 at Timworth (Nurse); on sugar at Gorleston in 1923 and Hopton (Mr). Yarmouth (Tr. Norf. Soc. 1899, 540). One on sugar at Mights bridge in Southwold, June 1935 (Baker); Sotterley, Lowestoft and Mildenhall that year (Btn).
