Recent Status: A less common species currently.
Life Style: A single brooded summer flying species that comes to light. The larvae initially mine before hibernation. In spring they feed on a variety of herbaceous plants in the shoots.
Identification: This species can only be reliably identified by examination of the genitalia. More Info 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.
