This Parachute Blue-Winged Olive imitation is tied on a barbless AHREX FW503 in a size 14.
The Parachute style of Blue-Winged Olive 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 time for a trout to intercept it (as it cannot escape). Only fish this pattern (and the Blue-Winged Olive Upright) 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 Blue-Winged Olive Upright).
This fly is only available in a size 14.
