Just weeks away or so are the March Brown hatches. The first significant, larger mayfly hatch of the season, it is well to study a bit on the habits of your March Brown. I say ‘your March Brown’ because there are several varieties depending upon where you reside. Rick Hafele goes over the East/West/In Between varieties and how they appear and behave. Time to tie those chucky clinger nymphs, emergers and duns. Read here at Rick Hafele’s Laughing Rivers post about March Browns. More & More re Western MB’s. Pay particular attention to that migration from faster riffles into the slower seams and edges.
