One time that for some reason sticks in my memory is when I was on a bridge in southern MN watching the Mayfly's. One just tipped over in mid flight and spun down into the water. I watched it as far as I could to see if a trout got it. No.
Until then I had not spent much time thinking about bugs dying in nature.
