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...my boss looked at that scope, and not only was it on sale for half price, there was an additional 15% off for Veteran's Day! I can now take really nice photos of all of these bugs I am working on! Here's a few for your enjoyment. A full post is coming on this project soon, just too busy with the work right now to pick out all the pics & etc.

Well I'd hate to meet some of those in a dark alley. Those are great pics. My son would love that.

Awesome Jonathon!

I also talked my wife into getting me this ringlight as an early Christmas present:

https://www.amscope.com/accessories/illuminator/ring-lights/144-led-lighting-direction-adjustable-microscope-ring-light-with-adapter.html

The overhead light built into the scope was a bit faint for some of the things I wanted to do, and at first I was using my fly tying light as an external source, but the ringlight is way nicer. Very bright uniform light up close above the subject. It does make manipulating specimens a bit trickier when using the 2X objective lens adapter though, just because the working distance is so short, but on balance I think it's very much worth it.

My only problem with the scope right now is that I've already identified all my preserved backlogged bugs as well as I can given my taxonomic resources and abilities, so I have to wait until spring to do much more with it.

I have a Unitron ring illuminator for my B&L StereoZoom scope at home, and it's currently on my Meiji Techno here at work because the danged halogen bulb burned out a month after I replaced it! Ring lights are the best, and this Unitron has some nice bells and whistles on it:

I love optics and the things you can see & photograph through them!

Folks - sorry I have been off for awhile, and not sure how often I will get back. If you are going to buy lights for miscrope photos, and general work, try to get a single head COB led with a flexible neck. Ikea sold some really great ones but no more. You could often get for 10 bucks. They must be out there somewhere yet. Now Ikea carries this.

It looks like it has a hard stem rather than flexible to the base. and the head looks larger in diameter than the old one. I don't know if it is as bright.
I think this is the old one.

be sure to get the 115V. not USB powered.

While the ring lights are good for many tasks, like Jason says, they won't get close enough at the higher magnifications, and they will leave a halo around many images you may not like. The small COB lights will fit even when your working distances get down to a cm or less.

one other item if you are buying scopes for macro/micro photo. Try and get one with with course and fine focus. The fine focus will make photograpy much easier, especially when you start stacking images.
