Question
What is this plant please. I live in south western Pennsylvania. Just found it laying on the ground a tree the edge of my woods. Oak and maple trees around.
Answer
Holly, you've photographed a gall from a species of wasp that lays it eggs in the leaves of certain oaks. These spherical galls are characteristic of this species of insect. Thanks for sharing your discovery.
