    Better if he posted a youtube video to reinforce his statement.

    Too many words.. too many words.

    I don’t know why this happens… I guess once a century they like to really “get nuts” at the Society of Entomologists Convention.

    Great fun for them, makes a mess out of some classic fly fishing reference books though.

    I guess it’s not that big a deal (Gray Fox or March Brown)… other than being different colors and sizes at all stages of the insect… they’re practically identical! :-P

    Reminds of that movie Twins… with Arnold and DeVito. :-D

    Maybe it's they’re way of stimulating the economy.

    Now a new wave of experts can regurgitate 65-year old knowledge, slap some new lipstick (Latin) on it, and you’ll be able to go out and buy all NEW books.

    Like the “Czech-style nymphing” craze…

    Re: March Brown/ Grey Fox

    I am new here and will have to figure out the platform here.

    Biot.

    You should treat them as different insects as they are. "As said to me by Dr Jeff Webb.

    "The bug is still the same bugs just the name changed".

    There are currently 3 forms that make up the vicarium complex. The forms are; 1 vicarium, 2 rivulicolum, and 3 fuscum, and they progress in color and size variation from 1 - 3. (3) being the lightest and smallest or as we knew it "fuscum". The most common one of the 3 forms seen is actually rivulicolum. Last year I reared over 300 samples in all three forms and from the genital aspect they technically for science purposes they should be seen as the same. Below are 3 samples from my rearing series.

    The first male is a (M vicarium / fuscum ) the female is a (M vicarium / rivulicolum ). The third one is a true (M vicarium) male to Walkers description. I hope when this posts the images will be bigger. I hope this is useful to you showing this series.

    I fish all three with the same fly just different sizes.
