Mothers Day Caddis

Overview:
The Mother's Day Caddis (Brachycentrus occidentalis) is a notable caddisfly species found in cold, fast-moving rivers and streams, particularly in the western United States. Emerging in early spring, typically around Mother's Day, this caddisfly is one of the first significant hatches of the season, providing a valuable food source for trout. The Mother's Day Caddis is medium-sized, with a dark olive to brown body and translucent, grayish wings. Its emergence marks an important event for anglers, as the hatch draws fish to the surface. Common hook sizes for imitations of the Mother's Day Caddis range from 12 to 16.

Nymph Stage: The Mother's Day Caddis nymph is about 0.75 to 1 inch in length, with a dark brown or olive body and a segmented appearance. These nymphs are typically found clinging to rocks and submerged vegetation in fast-moving water, where they feed on detritus and small invertebrates. They are active crawlers, moving along the substrate before emerging as adults. Fly patterns for Mother's Day Caddis nymphs tied on hooks sized 12 to 16 are effective. A dead-drift presentation near structure like rocks or logs is often successful for enticing strikes.

Dry/Dun/Spinner Stage: The adult Mother's Day Caddis, or dun, measures approximately 0.75 to 1 inch in length. Its dark olive to brown body contrasts with translucent wings that often have a grayish tint. The hatch usually occurs in large numbers around midday or in the early afternoon, when the insects take flight or rest on nearby vegetation. Fly patterns tied on hooks sized 12 to 16 are effective for imitating this species during its adult emergence.
