Identification
Galls are "globose, obscurely pointed, green [or] bright red, turning to brown or dark red." (Felt 1940)
Food
Galls are found on swamp white oak (Quercus bicolor), bur oak (Q. macrocarpa), and overcup oak (Q. lyrata).
Remarks
Parasitoids include 5 Sycophila spp. (Eurytomidae), one of which is pictured here:
