IN-0487 Knopper galls on acorns
Description: Close up of knopper galls on acorns of an oak tree (Quercus robor) caused by a gall wasp (Andricus quercuscalicis). This rather sticky gall develops on acorns in the autumn and varies from green to bright red. A central opening leads to a small egg-shaped inner gall where a single agamic wasp develops.
