Angler Notes

Why it matters

This is a high-value match-the-hatch bug because trout may key on it at several points in the hatch, especially when larger mayflies are scarce and more noticeable.

Imitation tips

Carry slim but slightly robust mayfly nymphs in red-brown or mahogany tones, soft-hackle or film-style emergers, upright-wing duns, and rusty spinner patterns. Keep body color warmer and redder than a generic brown mayfly when fish are selective.

Key life stages

Presentation

Start with a dead-drifted nymph before surface activity begins, then switch quickly to emergers or duns once you see rises. When fish sip gently in flat water, a low-riding spinner or cripple-style presentation is often the most precise finish.

Identification

Key features

A robust mayfly with the typical upright-winged dun and flat-winged spinner stages; anglers key on its larger profile and red-quill look compared with smaller mayflies.

Size

Generally a medium-large mayfly by trout-fly standards; commonly imitated around hook sizes 10-14.

Coloration

Usually matched with reddish-brown to mahogany bodies, darker thorax, and gray to smoky wings on duns; spinners are often tied with rusty-red bodies and clearer wings.
