  		Fig. 1. Arrangement of the flight room, with two different release locations and the positions of the two other observers for each release location. Gray box represents the calibrated space for video analysis. Black circles are the approximate positions of the two microphones.

  		Fig. 2. Three examples of bat pulse repetition rates (PRRs) emitted during attack sequences from the free-flight encounters as bats attacked free-flying mantids. An example is included from an escape (A), capture (B) and a trial where the bat dropped the mantis (C). The transition period (gray area) and slope (number) are indicated in each graph.

  		Fig. 3. (A) Percentage of escapes for all four experimental groups (within parentheses: number of escapes/number of trials). (B) Percentage of escapes due to drops for all four experimental groups (number of escapes due to drops/number of total escapes).

  		Fig. 5. The relationship between how close a bat came to the mantis and the slope of the transition period the bat emitted during the bat attack sequence. Faster transition rates from low to high PRRs did not allow bats to get closer to capturing the mantis.
