While most prominent in the central and eastern United States, the March Brown will also be found in many western streams and rivers, stretching as far north as Alaska. The common name of March Brown is a little deceptive as the largest and most epic hatches occur from June through July. Trout will actively feed upon this family of mayflies throughout their entire life cycle, but rare is the fish who can pass up the expired spinner as it floats by!
