I've never really noticed that but maybe they do avoid them. It makes sense.

What made me think of this in the first place was I was watching a program on tv where a physicist was explaining how water strider bugs are able to walk on water in physics terms. Its an amazing adaptation. (or creation, or intelligent design take your pick its amazing still)

And that naturally led to why don't fish eat waterbugs. naturally for me anyway.
