The Bibio was created in the late 1950’s or 60’s and was originally tied to represent the heather beetle for sea-trout on Loughs Furnace and Feeagh in Ireland.
The Bibio is taken for a large range of dark insects from duck flies to beetles. Bibio is a group of true flies which include the Black Gnat and Hawthorn. Water conditions will determine the size of fly to be fished. The Bibio is a good catcher of salmon and sea-trout. This fly is best fished as a bob fly in the surface film.
