Organ.sms often.evolve behaviours that in.rease or rein.orce the protection.from predators afforded by their morpho- logical defen.es. For example, mimetic an.mals may adopt postures or locomotory behaviours that emulate a characteristic fea- ture of their model to in.rease predator deception. Caterpillars with eyespots are thought to mimic sn.kes, an. when.threaten.d man. of these caterpillars adopt a posture that appears to en.an.e this resemblan.e. Herein.we evaluate the quan.itative stren.th of eviden.e of behavioural mimicry in.the caterpillars of 14 species by comparin. how closely a series of putative sn.ke-mimickin. caterpillars resemble sn.kes while at rest an. when.threaten.d. Specifically, we quan.ified the head morphology an. eye position.of a ran.e of sn.ke species, as well as the shape of the apparen. head （i.e. an.erior body segmen.s） an. position.of eyespots in.caterpillars restin. or in.their defen.ive posture. This allowed us to objectively examin. eviden.e for an.in.reased resemblan.e to either sn.kes gen.rally, or to Viperidae sn.kes specifically, upon.adoptin. the defen.ive posture. Widen.n. the an.erior body segmen.s durin. the defen.ive posture typically made caterpillars appear more viper-like as opposed to more sn.ke-like in.gen.ral. En.an.ed resemblan.e to vipers upon.moun.in. the defen.ive posture was apparen. on.y from the dorsal view. Laterally, caterpillars more closely resembled sn.kes in.the restin. posture an. shiftin. to the defen.ive posture in.tead reduced mimetic fidelity, Overall we foun. eviden.e for behavioural mimicry in.all 14 species examin.d. We highlight that objectively quan.ifyin. mimetic fidelity can.help iden.ify key features in.olved in.deception..
