Callirhytis juvenca
Callirhytis juvenca is a of gall wasp in the Cynipidae. Like other members of its , it induces galls on oak (Quercus species). The species exhibits the typical complex of cynipid gall wasps, with alternating sexual and that often produce morphologically distinct galls. Specific details regarding its host associations and gall remain limited in published literature.

North America; specific range boundaries poorly documented.
Host Associations
- Quercus - gall inductionSpecific oak not confirmed in available sources
Life Cycle
Has been observed to exhibit the typical cynipid pattern of alternating : a sexual generation that produces one gall type and an generation that produces another, often on different plant tissues or even different . The specific gall and generation timing for this species are not well documented.
