Is there an entomologist in the house?

This mayfly dun was way smaller than any golden stone.  About a size 14  

It was on the Niangua last September.

I captured 4 emerging nymphs during the hatch and had them in a film container with water, but when I got back home (3 days later) they had turned to mush.   I tied these nymphs from memory. 

But I'd really like to know what mayfly species it is.....so I can learn something about them.   

Entomologist gather samples and save preserve them in glass or plastic vials of isopropyl alcohol. they last a long time.   He always has vials with him when  we fish, he'll catch a fish or two, I look up and he's collection samples.   He'll pick up rocks or stand up stream and put a cheese cloth type net down stream into the river bed, then pick up or disturb rocks and bottom to dislodge stuff into he net.

Yeah, a 35mm film container with stream water certainly didn't work. 😁

Ethyl alcohol it what labs actually use, but isopropyl works and is easier to find

Interesting, this motivates me to research Mayfly types, I don't know how to tell the different types, swimmers, burrowers, etc...These Missouri  streams are pretty diverse.

A Hex?  Wow, I never would have assumed that.  Thanks!   

Kinda makes sense now that I think about it, because the area where they were thickest was a slower deeper trough with a silty bottom just down from our campsite.

                 See that was what I thought at first before you gave us the size. I know there are different ones out there. I have seen some cool hatches on the Osage near Taberville and the Sac near Osceola and even on the pond in my mom's yard.  All silty, muddy bottomed waters. These varieties were huge and, on the rivers, literally covered the willows on the shore. We stopped and I shook one and it was like a cloud appearing as they took flight.

Yeah the big brownish-gray mayflys that hatch here on the lake during late summer are supposed to be Hex's,. 

So I kinda assumed that all Hex's were the GIANTS of the mayfly world.    

Learned something cool tonite. 🙂

                                   Me too, not an entomologist but I tie and make fake bugs so therefor I am .

I had cropped the pic, but it was this part of my thumb that he was sitting on.

The pic makes him look like he's 2" long, but in reality he was only about 3/8" long.   Not counting the tails of course.

Plenty of Ethyl on clearance now, hand sanitizers.

Arthur getting to that thumb?  Looks like a funny crook in it..
