Q

I've noticed lots of caterpillars eating the leaves of my Birch trees--they look like inchworms. I've also seen them in neighbor's trees. Is there an infestation, and what can I do about it?

Answer(s)

A

I suspect you are seeing the boxelder leafroller, but you would need to bring some to your county Extension office to have a proper diagnosis and identification.

Read about the boxelder leafroller by downloading the USU Extension publication "Boxelder Leafroller", from http://extension.usu.edu/files/publications/factsheet/29.pdf
