The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic.

open access: yesPhyllomedusa: Journal of Herpetology, 2009
