Several species of Bee Assassins seemed to be resting, while night active flightless cactus beetles like the longhorn Moneilema gigas and the round little weevils, Gerstaeckeria sp., were coming out to feed under the protection of the darkness.

If you think about it, all this fantastic, and probably costly beauty must be geared exclusively towards interspecies predation avoidance, because there is really no (known) reason for caterpillars to signal to or even recognize members of their own kind visually. One could speculate of course that an egg-laying female might avoid an already heavily populated area to minimize competition for her own brood. I'm not aware of any research data supporting this hypothesis.
