This is a rad little beadhead leech from Hans @ Dakota Angler and uses a dubbing technique I rarely see. Clump dubbing is more like spinning deer hair on the hook than dubbing, but the result is a fluffy dub, similar to what you might achieve with a dubbing loop without the need to spin and tease out the dub.
Hook: Daiichi 1270 #10-14
Bead: Black tungsten
Tail: Marabou with pearl crystal flash
Body: Ice Dubbing
Hackle: Hungarian Partridge
Color variations include claret, black, olives and brown.
