This pattern is tied on a size 16 hook and represents a terrestrial black beetle. The under body is florescent green tinsel with a purple thorax. The over body is black feather fibers, some of the fibers are sprayed out to form legs. On top of the shank there is a tuft of orange fur which makes this fly very visible even from long distances. To fish the fly look for places where terrestrials are likely to fall in to the water: underneath tree bushes and beside any bank side vegetation both proving successful. Fish the fly in a dead drift style with the occasional twitch to simulate the beetle struggling in the surface film. This pattern is suitable for rivers and lakes from May to October.
