The Bibio Half Hog. Another modern variation of a classic : the bibio. Used mainly to imitate the heather fly, the bibio has become a fixed addition to many loch fishermen’s fly boxes. This combination sees the bibio meet the half hog, which was derived from the sedge hog, invented by Stan Headley. The half hog is a more flexible pattern to use as it can be fished as a dry fly, midge, sedge or as a sunken dropper. This is the bibio pattern but the basic principle of the half hog can be repeated with any colour you wish. The bibio pattern is deadly in late July and throughout August.
