Tying the Perfect Inch Worm Fly
This effective pattern is tied on small hooks (sizes 12-18) using stretchy materials like ultra chenille or flexi-floss in natural green or yellow tones. The segmented body mimics the distinctive crawling motion of a real inchworm, while a simple thread head keeps the design clean and realistic.
Why It Works
The Inch Worm fly imitates the larvae of geometer moths, a common snack for trout, especially in spring and early summer when these caterpillars are abundant near waterways.

Best Fishing Spots
Target overhanging vegetation along streams and rivers—where inchworms often drop into the water—for the most productive fishing with this fly.
