Last week I posted a photo of a yellow sally stonefly imitation on Instagram, and an observant viewer sent me an email noting that in the tying video I made with Tim Flagler, I did not tie in a tail like the one in the photo. They wanted to know why.
The answer is simple; I tie my Western version with the tail so it floats well in the big, fast waters that are found in Montana. Here in the East I tie them without a tail as our waters not as big and fast as those out West, and a sparser fly tends to work better. I will also carry some without a tail when out West for the spring creeks and fussy fish.
The trout mostly see the egg-laying adults, thus the egg sac on the fly.
