of the Lepidoptera of Belgium


Tortrix viridana  Linnaeus, 1758

A common species throughout Belgium, sometimes become a pest

The larva lives mainly on Quercus and sometimes they can completely defoliating the crowns. After clear-eating of his natural host plant, larvae disperse and attempt to feed on other deciduous trees. In the first two stages, the larva is feeding in young buds, later rolling the leaves.

The adults fly in one generation a year; onwards from late May till early July, but most observations during June. They are active from dusk onwards and come to light.
