Blue-winged Olives
Baetis

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.

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.

oh, gosh! isn't it amazing that any and everything associated with a fairly simple activity (see fish, catch fish, release fish) can get so wonderfully complex. and isn't it more amazing that this forum has folks who really like to make sure the rest of us know and understand the immense possibilities that exist in case we'd like to go into it a bit further. i'm serious in what i say here, just in case you think i'm being flip--not at all. i honestly had no idea there was more to dying things than Rit. the mere fact of different colored pheasant tails in my fly shop was in eye-opener! and then people straightenthat kinky calf's tail hair so it's easier to use.

the sheer inventiveness around here is just mind-boggling...;-) thank you one and all for taking the time and having the interest in your fellow anglers to share the knowledge!
