Monarch

A lot of the time, what I want is not a tripod—since, after all, I have a tripod— but some device that will prevent the sprig of vegetation something is perched on from moving. Without, of course, disturbing the perching thing in any way.
Going to be a big market when tractor beams come in, but until then, one must to some extent trust to luck. This is one of the cases of getting lucky on the timing. (About half of them are; the problem with the rest of them is that I was even less lucky about the angle, as the butterfly kept flipping its wings to deal with the slip-of-vegetation-nodding breeze.)
