Small Dot Wing Sedge

Overview: The Small Dot Wing Sedge (Neophylax fuscus), also known as the Autumn Caddis, is a medium-sized caddisfly species that is common in cold, fast-moving rivers and streams, particularly in the fall. This species is known for its distinct wing markings, with small dark spots that help identify it in the wild. The Small Dot Wing Sedge is active during the late fall months, typically from September to November, and its emergence provides a valuable food source for trout as they feed heavily before the winter months. The hatch often coincides with cooler water temperatures and may be more subtle than other fall caddis hatches, but it still offers an exciting fishing opportunity. Common hook sizes for imitating the Small Dot Wing Sedge range from 12 to 16.

Nymph Stage: The Small Dot Wing Sedge nymph is small, measuring approximately 0.75 to 1 inch in length. It has a slender, brown to olive-colored body with a segmented appearance. The nymphs are typically found clinging to rocks and submerged vegetation in moderate to fast-moving waters. They are bottom-dwelling insects, feeding on detritus and small invertebrates before transitioning into their pupal and adult stages. Nymph patterns tied on hooks sized 12 to 16 effectively replicate their size and shape. These patterns should be dead-drifted near the substrate or in areas where the nymphs are most likely to be found, especially during their pre-emergence migration.

Dry/Dun/Spinner: The adult Small Dot Wing Sedge, or dun, measures about 0.75 inches in length. It has a slender, dark brown to olive body with translucent wings that feature small, distinctive dark spots, which give the species its name. The adult caddisflies emerge in moderate numbers, often around dusk or in the early evening, and can be seen fluttering along the water’s surface or resting on nearby vegetation. They are important for late-season trout, as the hatch provides an easy and abundant food source. Dry fly patterns tied on hooks sized 12 to 16 can be effective for imitating this species, with patterns such as traditional caddis imitations, parachutes, or comparaduns replicating the insect’s size, color, and wing markings. Focusing on the water’s surface during the hatch will increase the chances of success, as trout key in on the insects as they emerge.
