[MAIPC] Ailanthus Herbivory

[paqinc at aol.com]

Aralia has a terminal leaf at the end of the compound frond; the leaf in her photo did not.  The photo also shows fairly long petioles which rules out a lot of other compound leaved species…this one has me stumped.  Is it a tree or a shrub?

Devil's walking stick (Aralia spinosa).

What looks like tree of heaven, has similar bark, and is tree-sized?  I will do some comparative looking.  I only know the various sumacs and black walnut.

That is not Ailanthus because the compound leaf is not odd pinnate, the notches are wrong and it is too rough.

The most likely one seemed to be the mite, except it's also called "leaf curl mite" not "patterned hole mite" so I'm still at a loss as to what could do such a distinctive look on all the leaves. Obviously it's not deer, and the moths seemed wrong too based on what little imagery I could find and general knowledge of feeding behavior (which I realize there must be more exceptions than moths I know)

Anyone know what's eating this tree of heaven?
