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.

Matt, that sounds like fun. I'll be in Oregon some of May, but when our schedules settle I'll see if I can get up to the Delaware. Looks like hatches may be a bit late this year, if local conditions match.

Well leave it from a prodigal trout fisherman to dredge up an old thread.

I am glad to see many of the old familiars still kicking around the boards. I have strayed from the clear and cold trout waters to the somewhat warmer haunts of those fiesty brown bass for the last few seasons. Every once in a while attempting to drag the good Doctor Martin over to the dark side. However it never seems to fail that this time of year finds me back on a trout stream and invariably dreaming of my to date largest dry fly trout (a snarky 23" Ausable brown ) that was facilitated by Spence.
I will try to not be such a stranger and hope all of you are doing well.
Regards,
JohnW
