Do you have pics???? Jap. bettle possibly, of maybe Leaf Miner???

I don't have a pic, but I do have one in captivity. He's a worm of some sort, bright green, w/brownish-gray jagged ridge along the back, maybe 1 1/2" long. He was the only one I found on the tree, and the property owner said she just noticed the damage yesterday!

Oh! there was also quite alot of other fuzzy black/brown insects which looked like large mealybugs along some of the branches
