I will continue to observe the trees.
It looks like the bees chew on the small young buds. When the leafs grow, the damage caused by that chewing, grows with the leaf. Causing holes, and other distortion. The edges of the holes are smooth and rounded over, like some healing took place.The brown spots are burning caused by me spraying the tree with a home made repellent containing water, soap, and garlic oil. It did not work for long. I just noticed that the leaf damage is on new leafs growth with in 4 inches of the end of the branch. The older large leafs closer to the trunk are undamaged. The older leafs grew before the bees were actively on the tree. The bees like to chew the buds on the end of the branch.
If it were moths, worms, or something else, I would think the damage would be more evenly distributed.
I still need to go out at night and look for bugs. Again, I have the tree full of pesticide. So, I would assume that any insect eating it would die. The bees are not eating, just chewing and collecting the resin. But, I am not an entomologist, so I could be wrong.
I don't want to kill the bees, I need their pollination services.
