What Are These Small Green Worms In My Trees?
If you’ve noticed small green worms hanging from trees with silk threads or unusual holes in your tree leaves, you may be dealing with cankerworms (also called inchworms). These caterpillars feed heavily in spring and fall, and while their feeding periods are short, they can strip leaves from trees and weaken younger or stressed plants if left unchecked. Similar to armyworms, they burrow into the soil to pupate and re-emerge as adults; fall cankerworms emerge as adults in the same season while spring cankerworms overwinter and emerge the following spring. Unlike armyworms, which damage lawns, cankerworms specifically target trees and shrubs.
