Zebra Caddis

Overview:
The Zebra Caddis (Macrostemum zebratum) is a unique and distinctive caddisfly species found in cold, fast-moving rivers and streams, particularly in North America. The Zebra Caddis is often seen in the spring and early summer, typically during the day. This species tends to hatch in moderate numbers and can create an important feeding opportunity for trout, especially during its adult emergence. Despite its relatively small size, the Zebra Caddis is an excellent target for anglers due to its contrasting coloration, which makes it easy for fish to spot. Common hook sizes for imitating the Zebra Caddis range from 14 to 18.

Nymph Stage:
The Zebra Caddis nymph is small to medium in size, measuring about 0.75 inches in length. It has a dark brown to olive body with a segmented appearance. These nymphs are bottom-dwelling creatures, found clinging to rocks and submerged vegetation in fast-flowing streams, where they feed on detritus and small invertebrates. The nymphs are active, crawling along the substrate before transitioning into their adult form. Fly patterns for Zebra Caddis nymphs, tied on hooks sized 14 to 18, are effective at imitating the nymph’s size and color. A dead-drift presentation near submerged structure is ideal for enticing strikes.

Dry/Dun/Spinner Stage:
The adult Zebra Caddis, or dun, measures approximately 0.5 to 0.75 inches in length. It has a dark body with distinctive black-and-white striped wings, which give it its recognizable "zebra" appearance. The Zebra Caddis emerges in moderate to large numbers, with the hatch typically occurring in the late afternoon or early evening. The adults are often seen fluttering on the water's surface or resting on nearby vegetation. Dry fly patterns tied on hooks sized 14 to 18 effectively imitate the Zebra Caddis, reflecting its distinctive coloration and size. These patterns are most effective when fished during the hatch period, where trout are actively feeding on the emerging caddisflies.
