Cnephasia pumicana
Cereal Tortrix

(Zeller, 1847)1022a / 49.053

Morley’s Final Catalogue: Not listed.

Recent Status: Can be a locally common species arriving as an immigrant, which governs its abundance near the coast. A recent arrival to the British list in 2010 with the earliest record in 1986.

Life Style: A single brooded summer flying species that comes to light. The larvae feed on the seeds of grasses and some other herbaceous plants. In some countries they can be pest on cereal crops.

Identification: This species is a small pale Cnephasia with a hint of brown. It is very lightly marked sometimes with only slight spotting, which distinguishes it from others in the genus.
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.
