70.028 Scopula (Calothysanis) emutaria (Rosy Wave)
fw: 11-13mm; Jun-Jul; poorly known - sea beet (Beta maritima)?; local on heath, bog and saltmarsh in England and Wales
Although Waring and UK moths both give this species as univoltine, I have found it on Foulness in June, August and September.
Hants Moths gives a 2nd generation Aug-Sep. Also note that the 2nd generation may be slightly smaller (fw 10.6 & 10.8mm in my specimens)

ID: Variable in ground colour from creamy-white to pale pink; in strength of markings; and in density of grey scales. Characterised by obsolescent 1st line, broad diffuse 2nd line usually fading before apex, dotted 3rd line. S.nigropunctata (Sub-angled Wave) is larger (14-16mm); S.immutata (Lesser Cream Wave) lacks the broad diffuse 2nd line - both have a narrow complete rather than dotted 3rd line and neither shows any pink colour.
