I'm going to share this with our entomology expert and see if we can get an id. Is this the only insect that you saw or are there more? (They may need more photos to get to an accurate ID.)
"I saw there was a single small caterpillar in one of the photos. I can't identify the type of caterpillar from the photo, but suspect is could be one of the leafroller/leaftier species (Family: Tortricidae) that affect apples and other trees and shrubs. The amount of leaf distortion (i.e. numbers of leaves affected and pattern) looks like more than I would expect from the caterpillar though. Perhaps this is a disease?"
Has the problem gotten worse since you originally sent in the photos?
