The March Brown
Male Adult March Brown
March Browns are large meaty mayflies that trout LOVE! This has to be one of my favorite hatches of the year to fish. March Browns are clingers and are found on the rocks adjacent to and within fast moving water. They often hatch quickly, especially on sunnier/warmer days, but sometimes will struggle to leave their shucks on cooler/cloudier days. I have frequently seen trout refuse many other mayflies and eat every one of these that goes down the lane. A great hatch to witness and have the opportunity to be a part of. March Browns will hatch sporadically all day and at times in heavy bunches especially during the late afternoons and evenings. The nymph has 3 tails and the adult 2 as it drops one upon hatching. I tend to like parachutes, burn-wings and compara-duns for the adults, although traditional Catskill ties or large variant style patterns can work great, especially when the water is thin.
