If you have one Parachute mayfly in your box, it should be the Parachute Adamsbut if you have two, the second should be the Brindle ‘chute. This fly is great for March Brown adults and Hecuba adults as well. But since it has Olive tones, it can work during a Green Drake hatch. The Brindle coloration uses orange, tan, gold, brown and olive making this an overall “buggy” representation.
