Andricus confertus, the convoluted gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in California in North America. This gall, with its pink, brain-like appearance, is actually a cluster of galls.[1] In summer, parthenogenetic female larvae induce these galls on the underside of valley oak leaves, along the midrib. Adult wasps emerge the following spring.[1] These adult females are brown with lighter markings, and are 2.5 millimetres (0.098 in) in length.[2]
