The Moths of Suffolk
2168 Viper's Bugloss, Hadena irregularis, (Hufnagel, 1766)

National Status : Former resident; presumed extinct

Habitats : Waste ground, roadside verges and fallow fields

Flight Period : Single-brooded; June to July

Larval foodplants : Spanish catchfly, on the seed-capsules

Records : Mildenhall (Dr B McNulty, 1963)

Morley's Final Catalogue : Asia Minor and Central Europe; in Britain confined to the Breck District of EAnglia, and most frequent in Suffolk part of it. There it was discovered as British at Tuddenham early in July 1868 by the Revd. A. H. Wratislaw, Head of Bury School, who also found the larva (Suff. Inst. iv, 1871, 219)," about ten miles from Bury St. Edmunds " (Suff. Inst. 4ly Journ., 1869, 23). There Norgate and other lepidopterists afterwards took it at Tuddenham where it appeared at light in 1889, Icklingham, Elveden, Eriswell and Brandon: before 1890. Later at Tuddenham, Herringswell and Worlington, light (Sparke, Entom. 1900, 40); several flying at dusk in June 1903 Thetford (EMM. xxxix, p. 226) and larvae there in 1932-3 (Bp); several in the Breck during 1913 (Nurse), where larvae were taken in 1916 (Harwood) and goodly numbers of imagines in 1931 (Trans. i, 232). This interesting species seems prone to spread, for Mrs. Mann has found it to be not uncommon at Bladder Campion flowers in Mettingham.
