Gallformers ID Notes
“
This midge induces distinctive swellings on the leaf veins and midribs of Q. muehlenbergii. They range from hairless to finely hairy, and the aged galls are a browner color while younger ones are a cream-white to yellow-green color. The galls create significant distortions on the upper leaf as well, contorting them. Observed in Ohio in May.
