    Re: Mr. Cahill and the Sulphurs

    I thought it was a Quill Gordon(Epeorus pleuralis).....as I get them every year around the same time, from a small creek out my front door....this was a female, obviously, but I also get them males and their Frank Poncharello sunglasses give them away....
    Epeorus require fast moving colds water with most importantly very levels of oxygen. But is your little creek is a spring, fast moving and all season. If so then Epeorus could be there. Epeorus are so fragile. Keeping them alive in a bucket for more than 2 hours to bring home is very hard to do. Every time I try to bring larva home alive more than 90% are dead in 2 hours.

    Yes..I aware of that. .it is very fast...small...and very clean.....it flows into C1TP waters.......like I said...I get male Gordon's also and they are unmistakable. ...

    Sounds like good spring insect habitat

    Here is one of the boys...I believe I took this two or three years ago

    Re: Mr. Cahill and the Sulphurs

    Epeorus pleuralis Quill Gordon, would be my first throw at it. The median femora markings also align with it. Tight set eyes and pointed frontale shelf are very suggestive of it.

    So, I don't like depending on luck.

    Do you know if anything has been done with mayfly DNA?

    I ask because I know a guy who runs a genetics lab.

    I have not approached him yet because I don't know enough to ask the right questions.

    See, I could capture a dark one and a light one.
    He could do the DNA test.
    Of course the DNA would be different due to the fact that they are two separate individuals, but I don't know if he would he be able to tell if they are the same species. If there was anyone doing work with mayflies, this may help him to figure out how close bugs of different (or the same) species are.
    You know what I mean?

    Anyway, I thought the DNA thing might be interesting...

    Re: Mr. Cahill and the Sulphurs

    DNA is a viable solution. Jeff Webb and 20 other authors together did a huge DNA profile study paper in 2013. I believe if I read that paper correct some 470 something Stenacron alone were sampled. I think in total they sampled and cataloged almost 5000 different mayfly species worldwide. All the bar-code information and more is available at this website call BOLD SYSTEMS. They have a online museum database that you can use to.

    This would be a monumental task. You'd have to know what you were looking for, I don't think you could just throw-up 2 mayfly genomes and look for differences. You'd also need a library where someone has done this already and has mapped out which sequences determine which characteristics and use this for comparison and control purposes.

    Roll up the windows Brian, you're letting the stank out.

    Re: Mr. Cahill and the Sulphurs

    That is all available at bold systems the DNA genetic mapping is completed as of 2013 they spent 3 1/2 years doing it and I believe there was 25 authors on that paper.

    Re: Mr. Cahill and the Sulphurs

    ​I believe I can likely answer why the tails on you carolina area so long. But here is the million dollar questions for you.

    1; what is the elevation from sea level where you are ????

    2; what color is the substraight of the water, Dark, Medium,
    or very pale light ???


    ---------------------------------------------------------------------------
    My guess is, the substraight is darkish chocolate brown :-)
    ---------------------------------------------------------------------------


    I have recently made a monumental discovery on Stenacron. There are NO HYBRIDS they are biogeographical and glaciation variants that are traceable, and I am studying them right now in real time.

    My isolated rearing plan of 1 on 1 rearing has created irrefutable evidence of morphological adaptation to specific substrates, and it is a genetic profile to each small area of substraight. The adults deposit eggs right where they hatch so the maculation profile is directly passed on, to that embryo, for that space in the stream or river. They even modify their physiology of their mouthparts to the conditions and local diet.

    1. Those guys came outta the same stream at 1480+/- feet above sea level.
    2. Stones and gravel consist mainly of dark grey shales; the silt/sediment is primarily light brown clay.
