Morley’s Final Catalogue: Our most abundant Tortrix, flitting everywhere along hedges at dusk. Assington to Gorleston.

Recent Status: One of the commonest tortricid species in Suffolk. A little less common than P. cerasana.

Life Style: A single brooded species appearing a little later than P. cerasana, flying from June to September. The larvae feed from spun leaves on a wide range of deciduous trees and shrubs. Young larvae hibernate and pupate in the larval habitation.

Identification: Suffolk has four species of Pandemis. Colour is not a satisfactory character for identification. P. heparana has a variable projection on the edge of both the basal patch and basal edge of the central band. The basal patch is effectively angled. P. corylana emerges later than the other species and is strongly reticulate over all parts of the forewing. The edge of the basal patch and basal edge of the central band are close to being straight and almost parallel. P. cinnamomeana male has a white face and the female has the hindwing tip tinged orange. P. cerasana male face is the same as the overall colour and the female shows no orange colour on the hindwing. Females of P. corylana, P. heparana and P. cerasana are larger, broader shouldered and show a more pointed apex than the males.
