That was a great read. I particularly liked that the dorsal orientation was strong enough that a light below the insect would invert it, even if that meant making it crash. I'm going to build an immersible lamp that I can put into a bucket with a layer of oil on the top (viscous fluid) so that the lamp is just below the surface of the oil. Based on the reasoning of this paper, it should result in flying insects inverting and doing a dive into the oil to their demise.
