What is another word for cankerworm?
Pronunciation: [kˈaŋkəwˌɜːm] (IPA) 
Cankerworm, also known as inchworm, looping caterpillar, or measuring worm, is a common name for the larvae of several species of moths. These caterpillar-like worms are known for their distinctive "looping" movement, in which they arch their backs and bring their rear ends forward, stretching to their full length before pulling their front end forward to repeat the cycle. They are small, slender, and often green or brown in color. Some other synonyms for cankerworm include spanworm, looper, and geometers, which are all used to refer to the same type of caterpillar. Regardless of the name, these insects can cause significant damage to trees and plants if left unchecked.
