I tie a slightly different version of that same pattern. I call it an easy zug bug. it out fished all of my other caddis nymph imitations 3 to 1 last year . the pattern is as follows
hook: size 14 lightning strike jf2
bead: 3/32 tungsten, slotted, silver
thread: 8/0 fire orange
tail: 3-6 peacock swords
rib: medium silver French wire
abdomen: peacock herl
hackle: speckled brown
it has worked better under an indicator than swung as a soft hackle
