Pseudoneuroterus saliens

The larva of the Cynipid gall wasp produces galls on Turkey Oak.

The spindle-shaped agamic gall (or like a slender cowrie shell or Cornish pasty) is attached to a twig, petiole or midrib, often several in a row. The gall is up to 3 mm long, hard, shiny, sometimes with a few length ridges, green at first becoming reddish brown and spotted, or brown later.

The sexual gall is on Turkey oak acorns; the acorn is slightly swollen and may be flushed red or with red 'tentacles'.
