Habitat
Associated with grape plants (Vitis ), occurring where plants grow in suitable conditions.
Distribution
Recorded from the United States, specifically including Vermont. Distribution likely corresponds to range of grape in North America.
Host Associations
- Vitis - gall induction on leaf petioles indicates specific gall formation on grape leaf petioles
Ecological Role
As a gall inducer, modifies plant tissue to create protected feeding and development sites. This represents a form of plant-parasitic interaction.
Human Relevance
Potential minor agricultural significance through gall formation on grape plants, though economic impact is not well documented.
Similar Taxa
