Question:
I have a "Pin Oak" tree. There are these (I don't know what you would call them)slug, not slug. I just planted this tree 3years ago. It stands 7 feet tall and is no wider than 3 feet. Any way, these so-call- ed slug things, start out very small, approx. 1mm wide by 2-3mm long. They grow in size, by eating or sucking the juice from the tree. They seem to eat or suck the new formed buds from the tree. I find them underneith on the branchs, but more so toward the ends. These pests are cleverly hidden. You wouldn't know their an insect until you look very close such as I did.

Ants are attracted by them. The ants can't harm them because they have some type of armor on the out side. The ants are how I found these pests. They grow in size and when you poke them, their pusy like. I never see them move. I only see new little ones each day. There killing my tree I planted for my son!!! Please, what are they



Replies:
Sounds like caterpillars.
