The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Neoleptophlebia Mayfly Nymph Neoleptophlebia Mayfly Nymph

Dorsal view of a Neoleptophlebia (Leptophlebiidae) Mayfly Nymph from the Yakima River in Washington

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Anyone try tying with TMC Aero Dry Wing?

It comes in great colors for posts on parachutes from natural duns to fl. Green and fl. yellow etc.

It's a poly material that is supposed to be hollow, three chambers really. I think I ran into it on Hans' Flytyer page under Dave Wilshire. I'm guessing there.

I ordered some from J Stockard and I'll let you know how it goes.

Have seen it, but haven't tried it yet. But when I run out of poly yarn (probably in about twenty years) I'd be tempted to give it a try. Seriously, let us know what you think.
