Double Bead Micro May #18

The Double Bead Micro May pairs a tiny mayfly profile with two beads for extra sink rate. It matches small Baetis while carrying enough weight to fish deep in fast water.

Use it as an anchor fly when small flies need to get down in heavy runs. Size #18 keeps the insect profile realistic for selective trout. Mayfly nymphs are on the trout menu nearly every day of the season, so a pattern like this earns a permanent place in your nymph box.
