The Double Humpy or commonly known as the "Tom Thumb" is a little gem of a fly for the dry fly enthusiast. The footprint of this fly offers itself up to being a great representation of a huge number of insects and the way in which it lands on the water ensures that it sits on the surface perfectly. The Double Humpy Bibio version is a particularly good Heather Fly imitation.Hook- Short Shank Size 12-10Overall length- Approx 16-20mmTail- Roe Deer HairBody- Black and Red seals furWing- Deer HairInternational Comp legal- Yes.
