Description
Gold Head Mayfly Olive Green Nymph. This fly is a precise imitation of a mayfly nymph, a staple in a trout's diet. It features a gold bead head, which adds weight for sinking and provides an attractive flash. The ribbed, olive-green body and realistic tail create a lifelike profile that is highly effective at fooling wary fish. This fly is a universal pattern for anglers worldwide.
Type of Fly: Nymph (specifically, a bead-head nymph). It is a direct imitation of a mayfly nymph.
Target Fish: This is a classic, go-to fly for all species of trout (rainbow, brown, brook), as well as grayling and other freshwater species that feed on aquatic insects.
When to Fish: This fly is highly effective year-round, but it is especially productive during mayfly hatches when these insects are actively moving from the riverbed to the surface. It can be fished successfully at any time of day, as mayfly nymphs are always present in the water.
Saltwater or Freshwater: This is a freshwater fly.
Best Fishing Locations: The G.H. Mayfly Nymph is a universal pattern that works well in a wide variety of freshwater environments. It is most commonly fished in rivers and streams, especially in riffles, runs, and the deeper pools where mayflies are likely to be found. The weight of the bead head helps it get down to the fish's feeding level quickly.
