Mayflies
The Guides Fly Box, the Mayflies will gradually start hatching soon. This is my version of the shaving brush emerger. I leave a few longer deer hair fibres poking out toward the hook end to imitate the legs. Try to cast it quickly to fish that have just risen to a natural, within 1.5m upwind of the rise and let it dead drift. Theses imitate the hatching mayfly that drifts slowly, can’t fly or swim. I have often seen the fly and the natural floating within inches of each other and the shaving brush gets taken more often than the natural. (Not to used while shaving)
