Leisenring’s July Dun Nymph

We wrap up the series of Leisenring’s favorite soft-hackled nymphs with the July Dun Nymph. No doubt Leisenring thought the July Dun matched the summertime bugs he encountered on his beloved Pennsylvania creeks. Certainly this fly could cover any number of small, dark nymphs that trout would think are good to eat.

I hope you enjoyed this little stroll down legacy fly pattern lane!

Leisenring’s July Dun Nymph



Hook: 15, 16
Silk: Orange waxed with colorless wax.
Hackle: One turn of very short, soft-rusty-dun cock hackle.
Tail: Three fibers of a ginger hen’s hackle tied very short.
Rib: Fine gold wire halfway up the body.
Body: Darkish-brown-olive seal fur.
Body: Medium-dun mole fur.
Tying notes: You don’t need to use precious tying silk on a pattern like this one (says the guy who used silk). Hen replaces cock for the hackle. Dark Olive Squirrel SLF Spikey Dubbing replaces seal fur. Leisenring uses mole in many of his patterns; a standard-issue mole skin will keep you in thoraxes till your old age. (Mike Hogue has some good skins at Badger Creek.) If you don’t have a mole skin, try rabbit.

Totally different but the same. Howzat? Curved shank instead of straight. Copper instead of gold. Brass instead of tungsten. Pheasant tail tail and no red thread collar. I like this bug as the bottom fly on my drop-shot nymph rig. What do you know? The trout like it there, too.

Hook: TMC2499SP-BL size 10-18
Bead: Copper (brass)
Thread: UNI 6/0 red
Tail/Abdomen: Pheasant tail fibers
