    Last April while fishing a central WA lake,I saw a hatch of what appeared to be both sized and shaped like Callibaetis mayflies only they were a very light grey,almost white.I did not notice any speckling on the wings,but then I did not get an up close look.The one fish I did catch was on a bleached out CB nymph.

    Hi jamma-

    Is it possible that you witnessed a mating swarm rather than emerging duns. Callibaetis ferrugineus hageni male imagoes, which would predominate (in number) in a mating swarm, often have hyaline wings absent any speckling.

    Thanks for the reply,but the ones I saw were popping out of the surface film.I am aware that the substrate can influence body coloration(I have noticed that Chopaka CB's are very dark,almost black)and wondered if the hard winter might have been responsible.At any rate,I tied up a bunch of emergers in case I ever encounter another hatch like this.
