Recent Status: One of the most abundant tortricid species in Suffolk.
Life Style: A single brooded species that flies from June to September and comes to light. The larvae feed on a range of deciduous tree leaves and buds. Herbaceous plants are occasionally used. The larvae may hatch in autumn and hibernate or hatch in spring. They pupate in a cocoon on the larval foodplant.
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.
