Oak Gall

DateWed 2008-10-01

A gall on the underside of an oak leaf, probably the result of infestation by the smooth spangle gall wasp (Neuroterus albipes). Each gall contains a developing wasp.  In the autumn they fall to the ground with the leaves and stay there until the spring.  Then the wasp emerges to mate and the females lay their eggs in new oak buds.
