Blue-winged Olives

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

Just for the sake of discussion. Is (the link above) the Baetis nymph we're imitating in PA right now? If so, would you consider the abdomen color a medium olive and the thorax a darker olive. I was turning over rocks yesterday on Spring Creek and the nymphs appeared to be a lighter color than my dubbing mix. I catch fish with them, but I'm always trying to improve. I may be mixing mine too dark.

I use the Flyfisher's Paradise recipe:

40% Dark Brown Rabbit (Hareline #24);
40% Black Rabbit (Hareline #7);
and 20% Olive Sparkle Yarn

Bruce, I think Steve made this up to represent nymphs right at the time of emergence, when they darken, though I suspect that nymphs often vary some in color. I have some of the FFP recipe dubbing and have used it a bit, but mostly tend to tie my baetis nymphs lighter and more olive.
