Leisenring’s Dark Olive Nymph

James Leisenring’s Dark Olive Nymph is sure to be popular among the finned set. For starters, it’s buggy as hell. Not only does it cover the pre-emergent Blue Winged Olive family, it’s also one of those flies that looks like lots of bugs in general, but not necessarily any one in particular.  That’s the good news. The flip side — if I may editorialize — is that I suspect a soft-hackled Pheasant Tail does the same duty, and is easier to tie. One way to find out!

Leisenring’s Dark Olive Nymph



Hook: 14, 15
Silk: Primrose yellow
Hackle: One or not more than two turns of the tiniest blue dun hen’s hackle.
Tail: Two or three very short, soft blue dun cock fibers.
Rib: Fine gold wire.
Body: Dark green-olive seal’s fur mixed with a little dark-brown bear’s fur (found next to the skin) spun lightly at the tail and quite heavily at the shoulder or thorax.
Tying notes: It should take me a few minutes to bang out Leisenring’s Dark Olive Nymph; when it takes longer than that to tie in the bloody “very short” tail, I curse my lot in fly tying and pine for the simplicity of the soft-hackled pheasant tail nymph. At this size, Angora goat (my standard seal’s fur substitute) would be an unruly mess. And since I’m right out of bear, I made the command decision to use Squirrel SLF Spikey Dubbing, dark olive and dark brown. I’m pleased with the results. A single dubbing loop for both abdomen and thorax.
