Egad! There are little worms, green and otherwise, making tatters
of my tree leaves--esp. those of the maples. Will the trees
survive this onslaught? Does anything, preferably nontoxic, stop
them? If something like dormant oil spray would work, I could at
least spray my little Japanese maples. On Monday, I will call my
arborist. Thanks.

Maybe Tuesday instead, because of the holiday?

Where are you in eastern MA? I've noticed some tattered leaves myself,
but haven't spotted the worms (yet).
