Fig. 5. (A) A representative oscillogram of sounds produced by a fifth instar Antheraea polyphemus larva when pinched five consecutive times with forceps. The larva first regurgitated (R) after the second pinch was administered. (B) Defensive regurgitation in a fifth instar larva in response to a simulated predator attack. (C) The percentage of regurgitating late instar larvae in one-, two- and five-pinch trials. (D) The number of pinches required to elicit regurgitation in late instar larvae. Larvae most commonly regurgitated after the second pinch.
