Morley's Final Catalogue: Apparently rarer than in 1890, when it had been found at Woolverstone, (not Ipswich by Bree); Glemham Magna (Bloomfield); Needham (L); Finburgh (Levett); Culford and West Stow (Wrt). Thence we know it only in a wood near Barham Green (Sparke) and a larva at Bungay (Mn).
Recent status: With the advent of electric light-traps, this species has become much more regularly recorded.
