Monnow May (deer hair)

Deer-hair baitfish dry
TroutSurface

A minnow pattern that fishes like a small baitfish in tumbling water, deer hair giving it pulse and buoyancy. Tied by someone who knows Iberian water — the minnows there are small and the trout are large.

Fish this when

Fish it during late spring and summer on river. Use it when the naturals are about and fish are feeding seriously. Have it ready for selective moments.

Why it works

It works because the profile reads as mayfly dun; large upwing adult. Straightforward pattern, proven result. Fish it with confidence when other flies don't move them.
