Hi Wendy!

Thanks for reaching out. Without a picture of the bug itself, we can't reliably identify what it is. It looks like the damage pictured is being caused by some sort of leaf-cutting insect and if there's webbing it could be a spider mite. Either way, the control methods will be essentially the same. As far as organic options for control you can remove the pests manually or if you're looking for a chemical or spray option you can use something with neem oil, bt (Bacillus thuringiensis), or spinosad in it. You should be able to find a product either online or at your local home and garden center. 

As far as the lumps go, no need to worry! Those are part of the leaf and produce a sugary substance that can attract insects like ants as a natural way to help fight off other insects like aphids! 

Have a great day!

Cheyenne



Hello. Same tree. Chewed leaves. Is this the bug?  Neem oil?
