Author, blogger and fly tier Matt Grobert show the steps for tying a March Brown dry fly tied Catskill-style. The March Brown dry fly is a classic pattern that still fools trout during one of the quintessential mayfly hatches.
March Browns (Stenonema vicarium) tend to hatch sporadically throughout the day, which makes this sparsely tied dun a great fly to fish even when there aren’t bugs on the water.
Grobert starts his March Brown with a throwback Mustad 94840 dry fly hook in a size 12. For thread he’s loaded a Rite Half Hitch Mag bobbin with a spool of olive Danville 6/0 tying thread.
