Even though the bugs often hatch in godawful weather and us fly fishers have spent many a March afternoon shivering, fishing a run as droplets of cold rain run down the sleeve of our casting arms, we would do it again tomorrow.

As the month of March begins to wind down the hatches of Blue Wing Olives, “Baetis” and Skwala Stones, “Perlodidae,” have been going on steadily since February a new player shows up. As late March and April arrives the days will typically start warming and the water temperatures will also go up which triggers the March Brown mayfly to start hatching. They can hatch in just about any weather. This is the “Rithrogenia Morrisoni” hatch. This large mayfly . . .
