Bats vs. Moths: an evolutionary arms race

MCZ 101, 26 Oxford Street, Harvard University

Bats and moths have been trapped in an evolutionary arms race for over 50 million years. Bats “see” the sensory world in sound and insects have evolved an array of tools to exploit echolocation to stay one wing beat ahead of bats. Moths have adapted ears and ultrasonic cries to avoid bats and jam bat sonar. Ms. Walden Gray will focus on the adaptations of tiger moths to avoid bat predation and introduce a species of tiger moth that has co-opted its bat ears for sexual communication.

The talk is free and open to the public. The meeting is readily accessible via public transportation. Parking is available in the Oxford Street Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets. Everyone is also welcome to join us for dinner before the talk (beginning at 6:00 PM) at the Cambridge Common restaurant on Massachusetts Avenue.

CEC meetings are held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (6 to 7 PM) followed by our formal meeting (7:30 – 9:00 PM). The latter begins with club business and is followed by a 50 minute entomology related presentation. Membership is open to amateur and professional entomologists.
