Many fly fishers love to be on the water at dusk, and for good reason. In times of low light, trout are less wary and are often more likely to feed on the surface. Their fear of predators, especially sight-feeding birds, is diminished, so the fish focus on eating available insects.
During warm summer days, many aquatic insects hatch at dusk, avoiding the harsh sun of midday. These emergences trigger feeding activity by the trout. From an angler’s perspective, dusk offers cooler temperatures, less wind, and gorgeous colors.
