Neoleptophlebia Mayfly Nymph Neoleptophlebia Mayfly Nymph

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.

Biography & Thoughts

I started fly fishing as a way to quit smoking. Every time I felt like smoking I would go outside and practice casting. I actually didn't start fishing with a fly rod until about 5 years after I quit smoking. The first fish I caught was an 18 inch Rainbow on a 4wt 8 foot Redington combo using a Royal Wulff. I've been hooked (pun intended) ever since. As an avid fisher growing up in Iowa I've caught some decent large mouth in and around the ponds and old gravel pits I lived around. But living in New Mexico I've come addicted to backpacking or hiking up to small mountain streams and lakes and fishing for small native cutthroats or browns. What I've come to appreciate about fly fishing is the strategy involved and having to think things through if I want to catch anything. This is especially true on small streams which one needs to employ stealth to be able to catch the spooked ones. I love how I have had to adapt and evolve fishing techniques in order to catch fish and I feel more as if I am part of nature as opposed to something that is invading it.
