Epinotia tenerana

Epinotia tenerana, the nut bud moth or alder tortricid, is a moth of the Tortricidae family. It is found from Europe to eastern Russia, China, Korea and Japan.

The wingspan ranges between 12–16 mm. Adults are on wing from July to September or early October in the UK. There are two generations in the Netherlands, with adults on wing from May to June and in August. In Poland, adults are recorded to fly from June to August or September.

The larvae feed on Corylus and Alnus, but also Betula and in rare cases even Quercus. The larvae live in the catkins of the food plant until the spring, then move into the developing leaf buds, making a hole at the base of the bud.
