Wasp Fly, Berners
Bristle Leech English 《fly》
American fly, an imitation of leech made by Gary LaFontaine in 1991. Because his idea of imitation is completely different from that of common fly patterns, it is introduced in detail from his book "Trout flies: proven patterns" (1993).
When LaFontaine was fishing in a mountain lake, at certain times he encountered trout preying on living things at the bottom in the shallows of the lake. He observed that when a trout approached the bottom, clouds of sand plumed up like smoke. Something was trying to escape from the trout when the trout had purchased and preyed on it. LaFontaine investigated what the trout was purchasing on, and it turned out to be a leech.
LaFontaine tied a fly using the hook upside down, and placed the bristle made of hard mono-filament line protruding perpendicularly about 5-6 mm from the shank. He cast the fly, and allowed it to sink to the bottom of the water before he retrieved the fly line. The bristle of the mono-filament scratched the sand, a sand cloud was stirred up, and the trout attacked the fly violently. He stressed in the book that this fly has a high success rate in a lake with a sandy bottom.
Isn't this a story like "the scales drop from the eyes" for a fly fisherman? No other person but LaFontaine could make a fly like this!
