Stimulator, watercolor, 9×12″, by Jean Krueger, copyrighted with all rights reserved, 2018
‘Stimulator’ is a classic trout fly pattern. It uses elk hair, wire and colored fiber.I’ve painted this example at a scale of 7 to1.Orivis describes is as an ‘attractor dry fly’ which sits up high on the surface of the water when it’s cast. It can be used in both slow and fast waters.
