Bibio

Created by Jeff Morgan

Uses

Imitates large terrestrial or semi-aquatic midges. The Bibio can also represent It a dark stonefly, wasp, adult cranefly, or even an emaciated cricket or hopper. Jeff Morgan says, "Don't shy away from size 8 or 10 imitations. It excels in these large sizes. Over the course of this summer in Yellowstone, I have found that a size 10 black Bibio has consistently outfished ant patterns for stubborn trout during non-hatch periods."
