Cluster Gall

Andricus lucidus

Cluster Galls were first recorded in the UK in the 1990s, having originated from the Mediterranean region. These galls result from the sexual generation of a gall-wasp. The flower-like clusters can reach sizes of up to 35mm across and consist of dish-shaped galls that interlock. Initially, the galls are green with a shiny, waxy surface, later turning reddish-brown and hard. The asexual generation of this gall-wasp produces Hedgehog Galls.
