Sphex Ichneumoneus
Sphex is the colloquial name of a particular kind of digger wasp. Daniel Dennett effectively uses this wasp’s burrowing routine to show how, even basic examinations of animal behavior can lead us right to the doorstep of causal determinism: the belief that everything (ie: particle systems, wasp brains, human courtship rituals, the universe) can be explained as states of affairs, resulting from some previous state(s) of affairs in a purely mechanistic fashion. When a causally deterministic outlook is applied to questions of agency, free will, and consciousness, the implications pile up fast. Some interesting explorations of this issue can be found in popular shows like Devs [FX] and West World [HBO].
