Description
Black Gnat, a classic and highly effective dry fly pattern. It's designed to imitate various small, dark-colored terrestrial insects, particularly adult black gnats, that either land on or are blown onto the water's surface. The fly's simple design, typically with a black body and hackle, is what makes it so successful at imitating a wide range of different "bugs".
Type of Fly: Dry Fly. This pattern is meant to be fished on the water's surface.
Target Fish: The Black Gnat is an excellent fly for all species of trout, and it can also be very effective for grayling.
When to Fish: This fly is a versatile, year-round pattern. It is especially productive in the spring and autumn when large swarms of gnats can be seen hovering over the water, and some inevitably fall onto the surface. It can also be a good choice during the summer when other insect hatches are not occurring. The fly is effective at any time of day, but it is a great "go-to" pattern in the late afternoon and evening when fish are actively feeding on the surface.
Saltwater or Freshwater: This is a freshwater fly.
Best Fishing Locations: The Black Gnat is a staple for rivers and streams, especially in slower-moving sections where gnats tend to swarm. It also works very well in the margins of lakes and still waters, particularly in calm water near reed beds or overhanging trees where the real insects are found.
