Epinotia nemorivaga

Description

Epinotia nemorivaga, the bearberry bell, is a species of moth in the family Tortricidae. It is found in Europe (from Fennoscandia and northern Russia to the Iberian Peninsula and Italy, and from Ireland to Poland) and Asia (China: Henan, Sichuan, Guizhou, Shaanxi). The wingspan is 10–12 mm. Adults are on wing in June and July in western Europe. The larvae feed on Arctostaphylos alpinus and Arctostaphylos uva-ursi. The larvae mine the leaves of their host plant. The mine starts as a corridor. Later, the larva leaves the corridor and starts making a large full-depth blotch. The larva leaves the blotch and moves to a new leaf, connecting both leaves with silk. The larvae are a dull grey-green color with a shining black head. They can be found from September to May.
