Something is eating my apple tree
I have two small apple trees that I planted last year. One is a Fuji apple and one is a Granny Smith apple. I have started to notice caterpillars like the one in the attached photo showing up on the Fuji apple and eating the leaves. So far none have shown up on the Granny Smith.
Can anyone tell what these are or suggest what to do with them? At first I thought I had eastern tent caterpillars, but I googled them and they don't look like this. For the moment, I am checking daily and removing them by hand.
Thanks in advance for any thoughts!
