Cnephasia communana
May Shade

(Herrich-Schäffer, 1851)1018 / 49.055

Morley’s Final Catalogue: Two examples of ' a rare form ' (Barrett) of this species were
taken at Copdock about 1900 (Hkg). Thetford in 1932 (Wlut).

Recent Status: Occurs in Breckland and Sandlings of Suffolk but is rare.

Life Style: A single brooded species that comes to light. Flying in early summer. There is no information on the immature stages in the UK.

Identification: This species is the first Cnephasia to emerge in spring such that any grey Cnephasia found in April or early May will be this species. It can be found later by genitalia dissection.
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.
