A plaque to many, a great bite for the fish. As with many terrestrials wasps (and bees, bumblebees) get a little “dizzy” during autumn when the first really cold mornings appear. It’s not uncommon for them to end up on the surface and catch the interest of a hungry trout. A great pattern when your fishing for rainbow trout in still water late on the season. 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.
