Zopheroteras sphaerula
Zopheroteras sphaerula is a species of gall wasp in the family Cynipidae, described by Weld in 1926. The genus Zopheroteras is part of the diverse cynipid radiation associated with oak galls. Like other members of its family, this species is presumed to be a specialist on oaks (Quercus), though specific host associations for this particular species require confirmation. The species has been documented through numerous iNaturalist observations, indicating it is not rare in suitable habitats.
