Movie 1. A MatLab simulation of a red bat (Lasiurus borealis) narrowly avoiding a noxious, sound-producing dogbane tiger moth (Cycnia tenera). The large red sphere represents the bat and the smaller black sphere represents the moth. The direction and size of the red arrow indicate the bat’s velocity vector. The direction and magnitude of the blue arrow represent the bat−moth bearing vector. The numbers (in degrees) near the bat’s velocity vector (red arrow) are the angular difference between the velocity vector and the bat−moth bearing vector. This angle (φ) was used to compute our measure of when the bats broke off their attack; the time, referenced to the time of minimum bat−moth distance, when φ exceeded 45 degrees and did not return below that value (Tveer). The blue numbers (in.cm) near the bat (red sphere) are the current distance between the bat and moth. The animation and audio are slowed down ten times.
Movie 2. A MatLab simulation of a red bat (Lasiurus borealis) widely avoiding a noxious, sound-producing dogbane tiger moth (Cycnia tenera). See Movie 1 description for details.
