Disholcaspis quercusomnivora
(Ashmead, 1885)
Disholcaspis quercusomnivora is a of in the , described by Ashmead in 1885. Like other members of the Disholcaspis, this species induces distinctive on oak trees (Quercus spp.), though specific gall and associations for this particular species are not well documented in available sources. The genus is known for producing hard, bullet-shaped or spherical galls on oak twigs and branches. As with many cynipid , D. quercusomnivora likely exhibits an with both sexual and phases.

Taxonomic note
The specific epithet 'quercusomnivora' combines 'quercus' (oak) with 'omnivora' (all-devouring), suggesting broad feeding or associations, though this interpretation is speculative without original description context.
