This Blue Winged Olive pattern in size #18 imitates a baetis mayfly struggling to hatch in the surface film.
BWOs hatch in cool, cloudy weather when little else is moving. Dead-drift it to rising fish during the hatch.
Restock before your next trip so you are ready the moment fish start rising. Present it with a drag-free drift, mending your line as needed to extend the drift through the feeding lane.
