Blie oak leaves with insect galls.
The galls are the puffy structures, most conspicuously in the center and at lower right
of the image. They are growths induced by insects, usually certain species of tiny
wasps, which serve to provide shelter and sustenance for the larvae which develop
inside the galls.
