Figure 3


Fig. 3. Spectrograms of three tiger moths responding to a played back bat echolocation attack sequence. The y-axis is frequency in kHz. Note the bat cries increasing in rate towards the terminal buzz-shortly after which the bat would envelop the moth in its wing and tail membranes. The sequences are presented in order of maximum duty cycle: (A) Amplicinia near mixta; 0.3% (B) Eucereon decora; 9.9% (C) Bertholdia femida; 31%.
