The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
The trout were sipping, gulping and leaping on these insects, but I and other anglers were unable to catch the fish. We were using very small Elk Hair Caddis patterns, but even these in size #18 and #20 seemed to big.
What sort of technique could a fly fisher use to attract a strike considering the tiny adult insects were NOT drifting on the surface, but dappling instead?
