Assuming one is photographing moving subjects of course, how commonly do folks employ focus trapping in macro photography?

I've just recently tried exploring a bit of macro (bugs, bees, and other moving things), and I'm curious whether focus trapping is useful or practical in this context.

I'm not sure what you mean. With trap focus, as in sports, you can pre-focus and wait for the subject to come into the frame. With macro, you're already in manual focus and might have a fraction of a millimeter that's in/out of focus. I can barely "trap" a flower in a slight breeze. The slight delay from a TTL flash can be a problem if I or the subject moves.

That might work for hummingbirds or butterflies with a long telephoto lens, but that's not macro.

Yes, it would seem that the depth of focus is not sufficient for such an approach to be feasible in macro work, which is what I suspected.
