Was wet wading yesterday and turned over a few rocks, looking for crayfish. I saw a couple of these clinging to the rocks. I have never seen before. Anyone have any idea what they are? 
 

And sorry for the crummy picture

That is the Canadian castrating moth larvae. They work their way to their victims middle finger where they imperceptibly deposit a single egg that travels through the body and lodges in the private parts, where it sits dormant for about 2 months before maturing and causing the member to fall off, and the cycle to repeat. There is no known cure, but fortunately they are not likely to infect humans unless disturbed from under stream beds...

It's a Dang Ugly Bug. I think Arnold summed it up nicely in the  movie "Predator" when the helmet came off.

Some of its legs were tucked under itself. I’ll try getting a better picture next time I’m out there, I saw quite a few 

Dragonfly nymph.

Stonefly  nymph, type would depend on where you are, but I would go with a #8 in black.

 

Thanks for the laugh and congrats on 5000 posts as this one was hilarious!!

It's a dragonfly nymph. 

Photos of the different types can be found on the internet.

I would catch them as a kid.  They can expel water from their gill cavity and sort of "jet" around in the water. 

And you should see how they capture prey.

 

 

Interesting, we found a ton of them in the muck along our lakeshore while looking for tadpoles.

Hint:  If you've seen the movie, Alien, you might have an idea... 

 

?

Dragonfly nymph seems to be the consensus, thanks for the help guys. I’ll still upload some better pictures within the next few days.
