Many mayfly nymphs are dark brown to olive in color. Not a surprise, just take a look at the bottom of most creeks, rivers, lakes and streams. It gives them a great camouflage. This nymph in size 3 is a great pattern that works on many occasions. As an example, it imitates large sized BWO’s, also known as Baetis. We recommend that you use a J:son Swivel for all your fly fishing, no matter what type of fly you are using. However, it is necessary to use a J:son Swivel whenever you fish a size 1 or 2 J:son fly.
