Wet Flies
March Brown Wet
The wet fly version of the March Brown is a classic swing pattern for early season fishing. Its mottled brown wings and gold-ribbed body imitate drowned March Brown duns and emerging nymphs rising through the water column — a presentation that trout intercept aggressively in spring.
