marchbrown_300.jpgFebruary approaches fast, and as water temperatures begin to rise (yes, it will happen) midges will give way to larger bugs. The March Brown is one of the first big flies to appear on late-winter waters, with trout keying in on nymphs and eventually dries.
This week Michael Yelton demonstrates how to tie a March Brown Nymph in his newest fly pattern video. March Browns usually begins to appear when the water reaches about 42 degrees. Nymphs tend to be fairly large — usually size 12 to 16 — and trout will key onto these early-seasons nymphs and their emerger stages before they do most other insects, if only because of their size.
