Mop & Glow Carp Fly
An over the top, ridiculously gaudy attracter fly. Call it cheap, call it cheating.. Whatever, this little neon attrocity gets their attention and slays them. In my area tailing carp are more than happy to sample non sensical vibrant attractor patterns. As well, glowing colors assist the novice, and those with sub 20/20 vision see the subtle take. Tie some up and put them in your box.
Just one of innumerable possible variations of the mop fly. This one tied with long soft hackle color, in neon, with dumbell eyes for a fast sinking hook up presentation.
One of the more productive carping holes near my home in central Tokyo.
