Western March Browns

Well its time of year when our very first large mayfly of the season will be hatching on our rivers and our wild trout is waiting with anticipation to get in to action.

March Brown nymph belong to the clinger group of mayflies. You find them among the rock in faster riffles or currents. Because very flat body profile and large overlapping gills , which they actually form suction cups enable them to cling and move on rocks. As other nymphs can loose their grip and get dislodge from the bottom , March Brown are very well secured on the bottom of the stream and only leave the bottom for the surface, where the dun emerge. They do drift long distance before do fully emerge and give plenty time for early spring trout to feed on them. March Brown are the first large mayfly of the season to emerge in the west. Beautiful big duns #14 will drift long way like sailboats before flying off to hide in stream-side foliage. Cooler, overcast days can produce longer and more predicted hatch. Trout at times can be very selective when feeding on these early season mayflies.

I love to fish for them with classic both , wet winged flies or Dry.
