Similar to Polly Rosborough’s Fuzzy Nymphs, Dave Hughes’ all-fur wet flies are simple and some of the most effective general nymph/wet patterns out there. You can vary the colors to match nearly any kind of underwater bug.
Hook: #10-16 1x long nymph/wet
Tail: Squirrel body fur
Body: Squirrel dubbing
Collar: Squirrel body fur, spun in a brush
