Sweeney Todd  English  fly
  British streamer. Richard Walker who was a famous fly-tier in Britain and Peter Thomas are the inventors of this fly. It is a black lure that can fish well. There is a variation called Sweeney Todd Nobbler. The origin of the fly's name stemmed from the front end of the body, i.e., the throat was red. A brief story of Sweeney Todd:
  In the first half of the 1800s in Britain lived a feared murderer whose name was Sweeney Todd. He was a barber, and when he shaved the face of a customer once he cut the customer's throat with a razor. Todd was captured, was sentenced to do cargo work on an ocean-going ship. His beautiful wife was raped by the judge, and she bore a child. The child was adopted by the judge and the wife was sold to a brothel. Todd fled to Britain and kept murdering. He made a pie with human flesh, and let the guests eat it at the pub. Finally, Todd was arrested and hung.
  The story spread, and a drama was written and performed in a theater under the title of "THE DEMON BARBER OF FLEET STREET, SWEENEY TODD". The play was performed frequently and Sweeney Todd became well known in Britain. (Information told by Erika Unterberger).
  The story seems a bit far fetched but the author simply wishes to explain the red throat of the fly which resembles the throat of the customer the barber cut with the razor. The throat hackle is crimson red and it expresses fresh blood flowing out. Going that far, the fly becomes a bit creepy, it is truly in British style, isn't it!
