The Black Gnat Parachute Dry Fly PARA4. These flies fall or get blown on to the water and trout are very partial to them. The Black Gnat is a pattern worth trying near the reedy margins of lakes.
Gnats are prolific from late Spring till the end of the trout fishing season.
They are bred on the land but spend the best part of their lives in the vicinity of ponds, streams and lakes. They may be seen in dense clouds over the water and fish will be rising madly to take their fill. At times like this a gnat pattern fished dry or wet will bring results. There are numerous dressings of the original black gnat pattern. They hatch in winter.
