notes
The larvae of Dasineura similis and Jaapiella veronicae cannot be separated macroscopically, and their galls strongly overlap. Abnormally hairy gals of leaf buds and petioles probably invariably are caused by J. veronicae, smooth ones (mostly?) by D. similis. Both species may also occur in galled flowers, and can only tentatively be identified by association with vegetative galls.
inquilines
parasitoids, predators
