"Mastering the Hellgrammite Fly: A Deadly Dobsonfly Larva Imitation for Trout"

How It’s Tied
The Hellgrammite fly is tied on a long-shank hook, typically in sizes 4 to 8. A lead wire underbody provides weight and segmentation. The body is built with black or dark brown chenille or dubbing to replicate the larva’s segmented appearance. Black or brown rubber legs mimic the natural larva’s multiple limbs.

What It Mimics
This pattern replicates the Dobsonfly larva, commonly called the Hellgrammite. These large, segmented larvae are a protein-rich food source for many fish species.

Where It’s Used
The Hellgrammite fly excels in rivers and streams where these larvae thrive, particularly in fast-flowing, rocky areas. Fished near the bottom, it mimics the larva’s natural crawling behavior, making it irresistible to predatory fish.
