Little Black Caddis

Overview: The Little Black Caddis, often referred to as the Black Caddis or Chimarra Caddis, is an early-season caddisfly that emerges in large numbers from late March through May, depending on the region. Found in fast-flowing streams and riffles, these small, dark-colored caddisflies are a favorite among trout. Their synchronized hatches and surface activity provide excellent opportunities for dry-fly fishing, especially in the afternoon when emergence is at its peak.

Larval Stage (Nymph): The larvae of the Little Black Caddis are case-builders, constructing small, tube-like homes from sand or detritus. They measure about 1/4 to 1/2 inch in length and are tan to dark brown. Effective larval imitations are tied on hook sizes 16 to 20. Fish these patterns with a dead drift near the bottom in riffles or runs, focusing on pre-hatch periods when trout actively feed on dislodged larvae.

Pupal Stage (Emerging Caddis): During emergence, the pupae rise to the surface in quick bursts, making them highly visible to feeding trout. Pupae are slightly smaller than larvae, typically 1/4 to 1/3 inch long, with dark brown or black bodies and lighter wing cases. Fly patterns tied on hook sizes 16 to 20 are ideal for imitating the pupal stage. Fish them just under the surface with a lift-and-swing technique to mimic the natural ascent.

Adult Stage (Dry): Adult Little Black Caddis are about 1/4 inch long, with jet-black bodies and dark, tent-like wings. Dry fly patterns tied on hook sizes 16 to 20 are excellent for matching adults. Focus on fishing during afternoon hatches or evening egg-laying events. Present the fly with a dead drift or subtle skitter across the surface to mimic the fluttering behavior of the adults. Target riffles, seams, and slower edges where trout are actively rising.
