This week’s Throw Back Thursday Fly is the IOBO Humpy TBT.

IOBO are the initials for It Oughta Be Outlawed. Those words in themselves should be all we need to know about the effectiveness of this fly.

The IOBO Humpy is credited to Jack Tucker of Pennsylvania, who created this fly pattern in the mid-1990’s. I read where Jack was trying to tie a CDC & Elk, but didn’t have the instructions, so he ended up with a fly looking something like this. He originally called it “CDC on a hook” and then “a ball of fluff”.

David Southall of Sunray Fly Fish in the United Kingdom wrote a terrific blog about tying this fly on their website – Sunray.

My tying directions are included at this IOBO Humpy link.

Enjoy…go fish!
