Little Sister Sedge

Overview: The Little Sister Sedge (Hydropsyche), commonly known as the "Spotted Sedge" or "Tan Caddis," It is one of the most important caddisfly species for anglers due to its prevalence and the significant hatches it produces, which attract large numbers of fish. The Spotted Sedge is typically tan or light brown in color, with its wings often featuring distinctive spots or patterns that give it its name. These caddisflies can be found hatching from early spring to late fall, making them a consistent food source for fish throughout the year. Common hook sizes for Spotted Sedge imitations range from 14 to 18.

Nymph: The Spotted Sedge nymph is typically 0.75 to 1 inch in length, with a slender, dark brown or olive body. It has a distinct thorax and is often found clinging to rocks and submerged vegetation in riffles or moderate to fast-moving water. The nymphs are bottom-dwelling creatures, actively feeding on detritus and small invertebrates before pupating and emerging as adults. Common hook sizes for Spotted Sedge nymph patterns are typically 14 to 18, with patterns that reflect the nymph’s slender body and natural colors.

Dry/Dun/Spinner: The adult Spotted Sedge Caddis, or dun, measures about 0.75 to 1 inch in length. It has a tan or light brown body with wings that are often mottled with spots or dark markings. These caddisflies emerge in large numbers, typically during the late afternoon or evening, often around dusk. Fish key in on these hatches, making the Spotted Sedge a critical food source during its emergence. The adult’s wings are held tent-like over the body when resting, and their drifty motion in the water can make them a natural target for fish. Hook sizes for dry flies generally range from 14 to 18.
