March Brown Spider

Rough-water spider

Trout · GraylingSubsurface

March and the March Brown won't hatch — but this spider, sparsely dressed in brown hackle and dubbing, fools trout into thinking something's about to. Works best in coloured water and a modest breeze.

Fish this when

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

Why it works

The spider style uses the hackle to suggest legs moving through the water. For March browns, which crawl actively across the bottom, this is exactly what trout see.
