Morley’s Final Catalogue: Felixstow (Gbs); Waldringfield (Wir)- frequent at Monks Soham light in July (Mly); Southwold (Ctw); Gorleston (D). Brandon on Scots-fir.

Recent Status: One of the commoner species of the genus in Suffolk.

Life Style: A single brooded summer flying species that comes to light during summer. The larvae hibernate before feeding. In the spring they initially mine and then feed in flowers or shoots of a variety of herbaceous plants.

Identification: This species can only be reliably identified by examination of the genitalia. More Info This is a larger species of Cnephasia but that fact alone cannot enable it to be identified.
Within the grey British Cnephasia species only two can be reliably identified without examination of the genitalia. C. communana flies early in the year so that any Cnephasia found during April or early May will be C. communana. C. pumicana is a small species that is very pale slightly brownish grey and very lightly marked such that the distal edge of the central band fades into the pale background colour. No other species is so small and lightly marked.
