What are the parts of an inchworm?

An inchworm, or measuring worm, typically has a segmented body consisting of three main parts: the head, thorax, and abdomen. The head features simple eyes and mouthparts for feeding, while the thorax contains muscle segments that allow for its characteristic looping movement. The abdomen, which is the longest part, is flexible and helps in the inchworm's unique crawling style. Additionally, inchworms have prolegs on their hind end that assist in gripping surfaces as they move.
