Author: Fitch, 1859
These galls were previously misattributed to Philonix nigra (Gillette).
Food
Quercus alba, Q. bicolor, Q. prinoides, Q. macrocarpa, Q. muehlenbergii (1)
Life Cycle
Galls are deciduous and begin dropping off the leaves before the end of July; some do not fall until October. Adults emerge in November and December, distributed over three seasons beginning the first fall. (1)
Remarks
Causes galls on the undersides of leaves in the white oak group: globular, 5-8 mm, covered with gray felt, one-celled. (1)
Galls with parasitoids or inquilines may be smaller, more sparsely haired, and less spherical; see examples (including the wasps that emerged from them) here.

Similar galls, 7.5-8 mm in diameter, on swamp white oak (Quercus bicolor) in Florida have been attributed to Philonix lanaeglobuli. (1)
