This Parachute March Brown imitation is tied on a barbless AHREX FW503 in a size 12.
The Parachute style of March Brown you see here is tied to imitate the insect which has hatched and is resting on the surface, waiting for its wings to dry out - this is an ideal for a trout to intercept it (as it cannot escape). Only fish this pattern (and the March Brown Variant below) once you can see fish rising.
When fishing with a parachute-style fly only apply floatant to the post, as you want the fly to fish in the surface film (not riding high on it like the March Brown Variant below).
This fly is only available in a size 12.
