Used the May Day pattern on a clear morning stream and caught three trout in under 30 minutes. The wing material made it stand out without looking too flashy. Great for beginners and experienced anglers alike.
Joanne Glover –
Felt the pattern worked well during a mid-morning drift. Trout were actively feeding, and the May Day stayed on the surface without sinking too quickly. A reliable choice for emerger action.

This pattern is simple but effective. I used it on a cold water stream and saw a lot of strikes. The color and movement mimic natural insects well, and it’s easy to tie.
