Joanne MacDonald –
This fly performs well during early spring hatches. The olive color and sparkle yarn make it look natural when drifting near the bottom. I’ve used it on several rivers and caught a few trout with it.
Sally Parsons –
Great imitation of early pupae. The sparkle adds a realistic touch, especially in slow-moving water. Works well in mid-water drifts. A bit delicate, so handle with care.
Faith Wilson –
I bought this after reading about LaFontaine’s original design. The attention to detail is impressive. It’s effective during fall hatches and matches the natural behavior of caddis pupae.
