Something eating my new blueberry leaves
Is there a common pest in the northeast that eats the new shoots of blueberry leaves as in the picture?. A few weeks ago I saw one small green caterpillar but I have been unable to find any caterpillar or bugs eating these leaves since then.
This is not the same damage as the bag worms I have on one plant. Those are easy to find now and I'm down to finding one or two a day.
I'm tempted to do a BT spray but don't want to bother without figuring out what pest it might be.
Thanks for any advice.
