Blueberry Leaves Stuck Together

Q: My blueberries are starting to turn blue but I noticed that something is binding the leaves together. It looks like the leaves have been bitten on the ends but they are then stuck together with something invisible. 

A: You have either a blueberry leaf roller or a blueberry leaf tier. If you disassemble the leaf fragments you’ll usually find a little caterpillar present. The easiest control is to squish the tied up leaves with your fingers, thereby crushing the creature inside.
