Overview
This realistic stonefly nymph uses translucent D-Rib over a tannish-yellow dubbed thorax and yellow thread underbody to create a segmented, lifelike profile. A brass bead, undersized by one hook size, adds weight up front, while a Golden Stone Scud Back wingcase and partridge legs enhance realism and movement. It's a moderately advanced tie that rewards precision and material control.

Behavior & presentation
- Natural Behavior
- Large stonefly nymphs crawl actively across cobble substrate, their segmented bodies and prominent gills visible. When dislodged, they tumble awkwardly through current.
- Where Trout Eat It
- Fish patrol bottom structure in riffles and runs, targeting tumbling stonefly nymphs during drift.
- How to Fish It
- Bounce along bottom with weighted rig, the ribbing creating segmentation that mimics the natural. Maintain bottom contact.
- Best Water
- Focus on riffle edges with cobble, pockets behind boulders, and current breaks near structure.
- Strike Type
- Feel a solid thump as fish attack the large nymph, or watch the indicator plunge.
Fishing strategy
- Rigging Suggestions
- This fly can be used as a single nymph setup or as part of a multiple nymph rig. It can also be effective as the weighted fly in a dry-dropper setup.
- Seasonal Timing
- The D-Rib Golden Stone is most effective in the late to early as this is often when the golden stonefly hatch occurs. Use this fly when fishing in western rivers, particularly those known for their golden stonefly hatches.
- Pro Tips
- This fly is weighted and designed to sink. It does not float and is best used in deeper runs where stoneflies are typically found.
Entomology
Golden stonefly nymphs exhibit territorial behavior, actively defending rocky substrate territories in highly oxygenated pocket water and boulder gardens throughout their multi-year development. Their deliberate crawling movements and occasional aggressive swimming bursts when threatened make them conspicuous prey items. Fish station behind structure knowing these large nymphs inhabit specific zones, ambushing them during spring migration when mature nymphs crawl toward shore to emerge on rocks and riparian vegetation.
