Figure 3


Fig. 3. Oscillograms of Antheraea polyphemus sounds recorded from fifth instar larvae. (A) Sounds recorded from an individual feeding on Quercus rubra leaves at 10 cm. (B) A click train, showing the typical click pattern of a larva after being pinched with forceps at 10 cm. (C) Three clicks from the train in B (denoted by black circles) with an expanded time scale showing the multiple components of clicks. The most typical pattern, a double-component click, is shown on the left. (D) Click spectra from five different individuals. The bandwidth varies, but in all clicks most energy is between 8 and 18 kHz.
