    What's a feasible design for a garden ornament that would give the illusion of a butterfly hovering around a flower when there was a breeze?

    There are solar powered versions of such ornaments such as I don't recommend them as cat toys, but this video gives a closer look at the mechanics of the ornament:

    If there was an obvious design, I'd expect that kite makers would have tried it as a novelty. However, the only flapping kites I've found on the web are in the shape of bats and they don't flap much.

    Use a windmill to drive the mechanism.
