Gallformers ID Notes
“
A midrib or lateral vein fold/swelling elevated above the leaf, with a long slit opening below. Sometimes multiple observed on a single leaf. The galls contain midge larvae. Observed on Quercus agrifolia in California in September and October.
According to Joyce Gross, Dr Gagne has identified larvae from similar galls as Macrodiplosis and Dasineura. Based on other galls, it seems likely that the Dasineura larva is an inquiline.
