Green Oak Tortrix

Resident and immigrant. Very common and occasionally abundant by day and at light in our leading oak woods. Generally distributed and seen wherever light is deployed, but high numbers are local and distinctly episodic. When at a peak T.viridana flies in higher numbers than any other lepidopteron in Sussex. Single-brooded fyling mainly from late May to mid July. Larvae feed on oak both evergreen and pedunculate. (Pratt, 2011).
