    Pryker, Your first pic is of a oak leaf gall, this is caused by one of many small insects, flies, or wasp that lay eggs in the tissue of the leaf causing a protective gall to form, no worries, it won't hurt the mighty oak. The second pic is of a webworm, which can be controlled with a number of insecticides, but unless there is a large population they won't cause long term damage.

    The owner of the second tree told me he though it was something called bagworms. I looked it up and bag worms form those little carcas looking bags and I did not see any of them.

    What do you mean by "Heck, Pecan Trees"?

    Thanks for the help!!

    I've heard that you are supposed to cut down the bagworms and burn them, I would be cautious if you burn them right in the tree. Hope that helps.

    For tent insects I prune out the tents, then 2oz / gal dish soap over the tree. GREAT control.

    There is a biological control called btk. We use it on tent caterpilliars up here. Maybe that would work.
