[1] Galls in which the larvae live and feed are formed along the midrib or petiole of white oak leaves.

[1] This species occurs throughout the eastern half of North America where its host plants grow.

[1][2] The galls of the sexual generation are round or club-shaped and formed on the petiole or midrib of the leaves in spring, with adults of both sexes emerging from galls in late June and early July.

[1][2] The gall is a firm swelling with a scar at the apex and contains several cells, each with a larva.

[6] The adults were first described by Homer Franklin Bassett in 1863 with the name Cynips quercuspetiolicola, though the galls had been previously described by Carl Robert Osten-Sacken.
