Jumping Oak Galls
These tiny (~1mm wide) structures (galls) from oak leaves contain miniature wasp larvae (Neuroterus sp.). These particular galls are commonly known as "jumping oak galls" due to their rather unusual behavior: as the galls mature, they fall from plants and the galls jump around until landing in a secure place (often under leaf litter) where the insect larvae will pupate and turn into adults. Imagine coming home from work to find millions of jumping galls on your driveway!

Laura HuberDo you have a photo of the galls on oak leaves that you could share? Do they form on both white and black oaks or just one family or the other?
