Could those hairy light brown balls in the photo in my last post be parasitic wasp galls? I had never heard of galls before, but after Googling some search words about these things, I see there are hairy/fuzzy ones. I guess the wasps hatch out and then the gall falls off the leaves??? I am going to go and take a few leaves off this tree and place them in an insect house and watch them to see what happens. If anyone has any idea about them, please share!!! It is oh so interesting!!! I will post pics on any developments!
