Explanation of Names
Quercus is the genus name for oak. "Mamma" is Latin for "breast," presumably a reference to the "nipple" on the gall.
Galls 1/4"-3/4" in diameter.
Galls are "globose, obscurely pointed, green [or] bright red, turning to brown or dark red." (Felt 1940)
Galls are found on swamp white oak (Quercus bicolor), bur oak (Q. macrocarpa), and overcup oak (Q. lyrata).
Parasitoids include 5 Sycophila spp. (Eurytomidae), one of which is pictured here:
