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

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

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.

Now this is one that slipped by me Ephemerella septentrionalis...Look at those long legs! I guess we may say that this bug doesn't qualify as a "Super Hatch", but what does anyone know of it? Has anyone other than Jason ran in to it? When does it emerge etc?

I have been meaning to send Jason a note asking him on how accurate is the color of the naturals he photographs to their true color? Are these their true colors or is something lost in translation?

If this bug exists in any numbers and the color is accurate...A natural pheasant tail would cover it nicely.

When I first started tying the "legs" on my PTN's were overly long...I could use them for this guy.
