Quigley Cripple   English fly
  American emerger (stillborn) pattern that is commonly referred to as Cripple. Cripple stands for a stillborn of mayfly that failed to hatch. This is a pattern developed by Bob Quigley in 1978 as the result of a considerable effort when he lived close to the Fall River in California. He now lives in Oregon.
  Fall River is a famous spring creek, also famous for its tough fishing, because the water is calm and clear, and the trout are selective. Quigley needed a special fly, he wanted a fly that had good visibility for his guests who were mostly elderly people. Therefore, when he attached a forward wing to the fly, it worked as an imitation of growing wings (budding wings), and it maintained its visibility - just like "Killing two birds with one stone."
  Quigley Cripple floats with a half-float and half-sink position at the water surface, and combined with a nymphal shack, it produces an excellent imitation of an emerger. Moreover, even if the major portion of the fly sinks, it becomes a vertical fly, and still keeps its power.
  Because this fly caught fish very well, it acquired widespread reputation, and it soon became a famous pattern. Many variations inspired by this pattern were produced afterwards. Recently, Quigley created a new pattern called Fluttering Cripple on which the wings are divided, the wing case is made of foam material, and the tail is made of transparent material.
