I thought I was done with this thread but my last wrapup post reminded me of something. I like to make flat, low-to-the-water grasshoppers and stonefly adults that don't land upside down. I make them that way as best I can. But it's not clear it really matters, especially with grasshoppers.
I floated the Yellowstone ten miles or so downstream from Livingston Montana in a wind storm a few years ago. The wind was so bad it went beyond annoying. It was flat out dangerous. If you get a high-sided drift boat sideways to a strong downstream wind (it usually blows upstream but not always) the wind has a tendency to lift up the upstream side of the boat, which digs the downstream chine deeper into the water. Sideways to a downstream wind like that, with the downstream chine digging down you'll flip right over if you smack sideways into a mid-river rock. I've done it and it isn't much fun.
And if you do get sideways to the wind it takes a lot of muscle to spin the boat half-way around, so the rear end of the boat punches straight into the gale force wind again. More muscle than some people have.
Anyway. On that late summer day I've never seen so many huge locust like hoppers. It was hopper time in late summer and the wind was blowing them out of the grassy fields and depositing them on the water in biblical numbers. The fish were going nuts, dimpling every where you looked. And I had to row, just to stay alive. We tried stopping and fishing but the wind was so bad it wasn't easy to cast. Trolling hoppers was killing the fish anyway. So we just went with the flow, drifting in the middle of the river where we were least likely to bang any hidden sleeper rocks.
And now the punchline. Every one of those hoppers landed on the water and kicked and struggled like crazy, in an upright orientation, like thousands of frantic panic-stricken miniature little latte blenders in the water. And then they gave up and died. And the minute they died they all turned upside down, dead drifting downstream with their yellow bellies pointing straight up.
The fish ate them both ways: dead upside down and dead drifting and alive and kicking and right-side up. It didn't seem to matter.
