Far and away the most effective Callibaetis nymph that you will use. The suggestive movement from the after shaft feathers off of a pheasant mimics the gills of a Callibaetis, and provides a profile and movement that you will not find on any other Callibaetis pattern. This fly produces during the strongest Callibaetis hatches, when fish snub away at other imitations. The Zallibaetis has been effective on both stillwaters as well as spring creeks. The best method to fish the Zallibaetis is to use either a floating or intermediate line with a slow hand twist retrieve or 4-6" pull n' pause retrieve.
