Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

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.

Well, it's over again for another year. Last night I turned in the grades for my Summer 2016 Introduction to Field Biology class. Now I have two weeks off before the Fall Semester begins. My folks were asking me, well what are you gonna do? Gee, uh, maybe go fishing??? Though, with our hot and dry weather things haven't been terribly exciting in that regard...

This class is always truly a joy to teach. Having been a field biologist for 32 years now, I feel this is exactly what I should be doing, and from my own days at the U of MI Biological Station, I have a model for what my class should be. This summer we caught a lot of fish, a variety of benthic macroinvertebrates, and saw some really cool plant life. The students were a good group, worked together well and had a lot of fun in the process. They even learned something! We visited forests of different types, dunes on the shores of Lake Huron, a cedar swamp with a tiny bog remnant (still retaining multiple classic bog plant species, including pitcher plants and sundews), Foote Pond, Clark's Marsh, the Au Sable River, the Pine River, Tuttle Marsh, and even [REDACTED] Pond, where I was glad I was wearing waders (while watching a 4" leech swimming around my waist).

Here's a few pictures to let you all in on the fun.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Wonderful Jonathon, good teachers are under paid and over worked. My wife is a para pro in our school district, so I know what these folks go through trying to educate these kids with all that goes on these days. I admire folks who the patience to work young folks. I can barely deal with people at the hardware anymore. Thank goodness I had 30 years at GM.

What fun, Jonathon. You are in inspiration as I prepare to get back in the saddle for fall semester.

Jonathon, I have to mention this, I went to high school at Flint Southwestern class of 75, we had a teacher there Mr. Ricky, aka ranger ricky, who had a place up north some where and would take kids who had no experience in the outdoors and work on his property. He was one of my favorite teachers in a place that had gone really wrong. I think that says something about a person, when I'm now going 60 years old, but Mr. Ricky made such a big influence on many lives back then. I wish I had your patience to work with young folks.
