A bug with rubber legs that quiver in the surface film , which does not have a extended body like other adult dragonfly patterns? so that you get more hook ups! The fish will nearly always take this Quiver Bug from behind ,just like they do when taking the naturals. If a fish looks like its not seen it give it a twitch and the take can be quite violent. Remeber in the film when its twitched and that rainbow trout hits it and comes clean out the water- SAVAGE TAKE! Colour - Black
