In this study we analyzed the three-dimensional flight paths and echolocation behavior of big brown bats (Eptesicus fuscus) attacking B. trigona in a flight room over seven consecutive nights to determine the acoustic mechanism of the sonar-jamming defense. Three mechanisms have been proposed: (1) the phantom echo hypothesis, which states that bats misinterpret moth clicks as echoes; (2) the ranging interference hypothesis, which states that moth clicks degrade the bats' precision in determining target distance; and (3) the masking hypothesis, which states that moth clicks mask the moth echoes entirely, making the moth temporarily invisible. On nights one and two of the experiment, the bats appeared startled by the clicks; however, on nights three through seven, the bats frequently missed their prey by a distance predicted by the ranging interference hypothesis (\u223c15\u201320 cm). Three-dimensional simulations show that bats did not avoid phantom targets, and the bats' ability to track clicking prey contradicts the predictions of the masking hypothesis. The moth clicks also forced the bats to reverse their stereotyped pattern of echolocation emissions during attack, even while bats continued pursuit of the moths. This likely further hinders the bats' ability to track prey. These results have implications for the evolution of sonar jamming in tiger moths, and we suggest evolutionary pathways by which sonar jamming may have evolved from other tiger moth defense mechanisms.<\/jats:p>","DOI":"10.1242\/jeb.054783","type":"journal-article","created":{"date-parts":[[2011,6,22]],"date-time":"2011-06-22T17:15:54Z","timestamp":1308762954000},"page":"2416-2425","source":"Crossref","is-referenced-by-count":37,"title":["How do tiger moths jam bat sonar?"],"prefix":"10.1242","volume":"214","author":[{"given":"Aaron J.","family":"Corcoran","sequence":"first","affiliation":[{"name":"Wake Forest University, Department of Biology, Winston-Salem, NC 27106, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse R.","family":"Barber","sequence":"additional","affiliation":[{"name":"Boise State University, Department of Biological Sciences, Boise, ID 83725, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nickolay I.","family":"Hristov","sequence":"additional","affiliation":[{"name":"Center for Design Innovation, Winston-Salem, NC 27101-4019, USA"},{"name":"Winston-Salem State University, Department of Life Sciences, Winston-Salem, NC 27110-0003, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William E.","family":"Conner","sequence":"additional","affiliation":[{"name":"Wake Forest University, Department of Biology, Winston-Salem, NC 27106, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042423033034700_R1","doi-asserted-by":"crossref","first-page":"2637","DOI":"10.1242\/jeb.02295","article-title":"Tiger moth responses to a simulated bat attack: timing and duty cycle","volume":"209","author":"Barber","year":"2006","journal-title":"J.
