These are the Predators. They actually look kind of cute; not at all scary. The idea is that fish will go for them. I do not have proof of that since Len tied these for a youth fly fishing event that is sponsored by the Michigan Fly Fishing Club and has not actually tried to catch fish using these little guys. The club was asking some members to donate about 20 of their favorite flies so they can give each of the youth attending the class a selection of flies to start them off right for fly fishing. Len chose the Predator as his contribution. Cute little buggers; aren't they?
