A black mayfly? Well, it might come as a surprise, but there are actually many species of mayflies that are really dark in color, especially in their spinner stage. As an example, many species within the Baetis family can be almost black. But black is also a fantastic color when ever you want to give the fly a perfect silhouette that is easy for the fish to see against a darker sky, such as on really cloudy summer evenings. 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.
