The prey recognition system in the predatory behavior of T. tachydromoides was analyzed experimentally using unpalatabe Pryeria moths and edible mealworms. None of the Pryeria moths were either killed or eaten, while all the mealworms attacked were eaten. The learning of visual avoidance by T. tachydromoides, in which the lizard associates the unpalatability of Pryeria moth with its appearance and avoids it, seemed to exist, but its process appeared to be very slow. In the course of predatory behavior, the lizard first recognized the prey visually, but then checked it strictly through chemical cues. This suggested that not only visual but also other sensory cues such as olfactory and gustatory stimuli derived from the prey were necessary for the efficient avoidance learning in this lizard.
