Hendrickson
The April mayfly that makes freestone anglers cancel meetings. Reddish/brown duns and a strong nymph drift beforehand.
Taxa: Ephemerella subvaria (classic Hendrickson)
Hendricksons on and trout rising = go. Size and color beat brand names.
Life stages
Mayfly path: egg → nymph → dun → spinner. Classic eastern Ephemerella hatch.
When it matters in the Southern Apps (NC–VA)
April prior on SE freestones; can shift with elevation and spring warmth.
Matching artificials & techniques
Mimic the stage the fish are eating — size and silhouette first. Patterns are common SE shop language, not a brand list.
Hendrickson nymph, Pheasant Tail, Hare’s Ear (#12–16)
Dead-drift before and during the hatch build.
Hendrickson dry, Red Quill, Comparadun
Match the reddish body; present to risers.
Red Quill Spinner
Spent patterns in soft water after the main hatch.

Regional note: Taxonomy and stage language follow standard aquatic entomology (Ephemeroptera / Trichoptera / Plecoptera / Chironomidae). SE timing is a regional prior from the hatch calendar — confirm with thermometer, seine, and local shop/agency charts.
