• Acraspis

  Acraspis is a genus of gall wasps in the family Cynipidae. Species in this genus induce distinctive galls on oak leaves (Quercus spp.), including the jewel oak gall and oak pea gall. The genus exhibits specialized host associations with oaks and has been documented to employ spacing strategies that reduce parasitoid attack rates.
