The mayfly genus of Siphlonurus, commonly known as Grey Drakes, are an important still water and slow moving water family spanning the US and Canada. Swimming quickly to the surface in a hatch that lasts a number of months, it is the adult Dun and Spinner life stages that will linger around the water for several days after their emergence, making the Extended Body Foam Grey Drake a killer pattern during the hottest part of the hatch!
