I have already mentioned Neuroterus quercusbaccarum (My blog, 'Rolling our sleeves up', 18 May). This is a curiosity in that this tiny wasp will induce the production of differently-shaped galls depending on where and when the attack occurs. The photograph shows the gall produced on the leaf of a Pedunculate Oak, Quercus robur.
