Habitat
Associated with oak trees (Quercus ), which serve as for gall induction.
Distribution
Neotropical region.
Diet
Larvae feed on plant tissue within galls induced on oaks.
Host Associations
- Quercus - gall All induce galls on oaks in which their larvae live and feed.
Life Cycle
Larvae develop inside galls induced on oak trees. Specific details of , larval, pupal, and stages are not documented.
Behavior
Induces galls on oak trees. Gall induction is the primary known behavioral trait.
