In the PNW, caddisfly hatches are a major food sources for trout from spring to late fall. Having the right caddisfly patterns can make the difference between catching just a few fish or many.
Bob Quigley will be remembered for the many innovative fly patterns he originated for fishing trout and steelhead. When copying nature Bob threw the book away, often starting from scratch when portraying some hitherto unseen facet of a hatch. Often his flies were immediately copied by other tiers and anglers. In many ways Bob Quigley had the same effect on fly tying as Bob Dylan had on music...genius and originality.
