Red Quill
Epeorus spp.
Description
The Red Quill (Epeorus species, often E. pleuralis or similar) is a classic early-season mayfly that holds a special place in fly fishing lore. Often associated with the Hendrickson hatch (where the darker male subimago is called the Red Quill), these insects are medium-sized (#12-14) with distinctive reddish-brown bodies and slate-gray wings. They are "clingers," adapted to fast, turbulent water. The Red Quill hatch typically occurs in the afternoon during the warmest part of spring days, exciting anglers eager to shake off winter.

Habitat
Red Quill nymphs are true clingers, evolved with flattened bodies to hold virtually flush against rocks in fast, turbulent currents. They inhabit the heavy water of riffles and runs in freestone streams. Because they need highly oxygenated water and clean substrates to cling to, they are sensitive to pollution and siltation. You'll find them in the fastest fishable water, often right in the white water of heads of pools and heavy pocket water.
Behavior
Emergence usually happens in the afternoon (1PM - 4PM) when water temperatures peak. Since nymphs live in fast water, the hatch often occurs in riffles. However, adults may drift into pools. Uniquely, because some species hatch on the bottom or quickly in the film, the wet fly swing or deep nymphing can be more effective than dry fly fishing at the start of the hatch. Duns ride the current like little sailboats, and because they emerge in fast water, trout must make decisive, aggressive takes.
Fishing Information
Seasonality March through May (Spring), depending on water temperature and location.
Tactics
- Fast Water Focus: Target the heavy riffles and pocket water where nymphs live.
- Wet Flies: Swinging a wet fly or soft hackle is a traditional and deadly method for Red Quills.
- Blind Casting: Duns emerge sporadically; covering water with an attracter pattern or specific imitation works well.
- Afternoon Peak: Plan your fishing for the warmest part of the day.
Recommended Patterns
- Nymph: Pheasant Tail (dark), Prince Nymph, Hare's Ear
- Wet Fly: Red Quill Wet, Soft Hackle Pheasant Tail
- Adult: Red Quill Dry, Quill Gordon, Adams (dark)
Conservation Status
As sensitive clingers, Red Quills are excellent bio-indicators. They disappear quickly from streams impacted by acid mine drainage, sedimentation, or thermal pollution. Conservation efforts focused on watershed health and riparian restoration are vital for these fast-water specialists.
