Silk Button Spangle Gall, Neuroterus numismalis, Cynipidae, Hymenoptera. Gall wasp galls on an oak leaf. Neuroterus numismalis is a gall wasp that forms chemically induced leaf galls on oak trees. It has both bisexual and agamic (parthenogenetic) generations and forms two distinct galls on oak leaves, the Silk button gall and Blister gall. The galls can be very numerous with more than a thousand per leaf. Neuroterus reaumuri, N. vesicator, Spathegaster vesicatrix, Cynips numismalis, and C. quercus-tiarae are previous binomials found in the literature. Image shows leaf underside on left, and topside on right.
