Salmonflies
Pteronarcys californica
The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Here's a Discovery article about a wild trout with two heads , found in Idaho. It might be linked to selenium pollution from a mine there. Thought this might be of interest.

Sobering stuff Luke! We went through this before in the east with the coal mines and native brookies...We treat fresh water, something we all need, in such a reckless manner.
I had a poli-sci professor in the 70's who used to talk about our "toilet bowl" mentality...He would say, "As long as it can be flushed away, down the drain, and away from us, we really don't give a damn it's effects for those downstream of us. It's no longer our problem."

Trouble is, and most people don't think about it, most of our drains are connected to someone else's faucet!

By that logic, so are our toilets. Hmmm... Glad I live "upstream"! :)LOL

It truly is sad how we treat our water.. BLUE gold is the most prominent resource, i just hope it will always be around in a pure form!
Most of us fish our whole lives..not knowing its not the fish that we are after.

Selenium. Interesting. Up here we have so much selenium deficiency that I have to give selenium shots to my goats.
I am a strong supporter of mining, but still if you are going to mine then do it safely.

Notice I said "might." Some of these oddities occur for many other reasons. Often people find one unusual morph and draw unnecessary conclusions. Coincidence in time and space does not necessarily indicate a cause. On the other hand, it may very well be connected.
