  1. Tiger Moth Jams Bat Sonar Review of a scientific article by: Amy Worth, Dimitri Lamisere, Idil  Osman, Bianca St. Louis

  2. Background and Rational • Bats use echolocation  • Moths ultrasonic clicks       have previously been shown to alert bats and to startle • Scientists hypothesize the moths jam bat sonar however, evidence is lacking for this so called jamming

  3. Hypotheses Moth clicks function to: • Alert of warn  • "warning of unprofitability" •  Startle • Sonar interference or jamming   • diminishing a bats ability to determine the moths distance • clicks may sound like an object that does not exist  • Clicks may confuse bats  

  4. Method Used four bats • 3 juvenile, 1 adult 16 tethered moths • with controls being moths with clicking disabled and moths of other species that do not click  Placed in a flight room equipped with high speed infrared cameras and an ultrasonic microphone Bats were given one minute or 5 attempts for each moth Experiment lasted nine nights

  5. Conclusion

  6. Suggestions and further question Use more bats and moths They could have tested more than 9 nights Are there other species of bats that have the same reaction towards moths that can click ultrasonically?
