Ephemeroptera · Ephemerellidae

Hendrickson

The April mayfly that makes freestone anglers cancel meetings. Reddish/brown duns and a strong nymph drift beforehand.

Taxa: Ephemerella subvaria (classic Hendrickson)

Bait lens

Hendricksons on and trout rising = go. Size and color beat brand names.

Life stages

Mayfly path: egg → nymph → dun → spinner. Classic eastern Ephemerella hatch.

Nymph — Pre-hatch nymphs before the April rise.
Dun — Reddish-brown body — classic Hendrickson look.
Spinner (Red Quill) — Red Quill spinner talk after the dun.

SE timing is a regional prior from the hatch calendar — confirm with thermometer, seine, and local shop/agency charts.
