This fly performs well during early spring hatches. The sparkle yarn catches the light just right, making it look natural in the water. I’ve used it on several rivers and caught a few trout with it. Good quality and matches the description well.

The tan color blends well with the riverbed, and the sparkle effect is subtle but effective. I’ve fished it during mid-spring and saw some strikes. A reliable pattern for early pupa hatches.

I bought this after reading about LaFontaine’s original work. The fly matches the description exactly. It’s easy to tie and works well in slow-moving streams. Great for beginners and experienced anglers alike.
