Used this pattern on a quiet lake in the morning and caught three trout in under 30 minutes. The imitation is very natural and the size matches what fish are feeding on. Great for when they’re not biting on standard flies.

Felt like a real emergent bug when I fished it in a slow stream. The color and movement are subtle, which made it work well in low light conditions.

The pack came with six flies, all in good condition. I’ve used it in multiple fishing spots and it consistently produces when the water is still and fish are cautious.
