DESCRIPTION: A lantern-style gall that can be found in large numbers. Ovoid and pointed in appearance these tough, thick-walled galls start greenish and become reddish with age. Galls containing male larvae are narrower and smaller than those containing female lavae. When the larva is full grown the gall drops to the ground, and the larva closes the opening with silk. The larva hibernates in the gall and pupates in spring. Trees affected by this gall tend to produce smaller leaves. DISTRIBUTION: Deemed extinct in Britain but with several records over the last few years primarily from southern areas. HABITAT: On the leaves of Beech trees (sometimes on Chestnut), usually found high up in the canopy but can be found low down.
