What's eating these apple/pear leaves?

[Thomasc19]

1 Pear and 1 Apple tree are eaten like this - all but the stem of the leaves. I have japanese beetles which make the leaves look like "lace" but not like this. Only these 2 trees out of 90 are like this (Too high for deer to get)

 

[Charles Clear]

I'd say grasshoppers

 

[Prof.Kent]

Deer can stand on their hind legs to reach higher, when you don't have them fenced in.
