Bats vs. Moths: an evolutionary arms race
MCZ 101, 26 Oxford Street, Harvard University
Jessica Walden-Gray
Jessica Walden-Gray, Boston 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.

Consequences of multiple species invasions: a native butterfly confronts exotic plants and parasitoids
MCZ 101, 26 Oxford Street, Harvard University
Dr. Frances Chew
Frances Chew, Professor of Ecology, Tufts University
Exotic invasive species pose challenges to native species encountering them
for the first time. In the 1800s, the native mustard white butterfly flew
in Harvard Yard. Since then it has been affected by serial invasions of
garlic mustard, parasitoid biological control agents for the related
cabbage white butterfly, and other exotic plant species. Despite its
current threatened status in Massachusetts, the ecological stage is now set
for recovery and population growth of this butterfly – an unintended
consequence of recent species introductions.

Parking is available in the Oxford Street Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets.

The Origin and Maintenance of Mimetic Wing Pattern Variation in Butterflies
MCZ 101, 26 Oxford Street, Harvard University
Dr. Sean Mullen, Boston University
The link between divergent natural and sexual selection of adaptive traits (e.g., mimicry in butterflies) and the origins of barriers to gene exchange between closely-related populations (i.e., speciation) can provide insights into the origin and maintenance of biological diversity. These topics are the focus of Dr. Mullen’s studies of mimicry of Limenitis butterflies and will be the subject of his CEC talk.
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 6:15 PM) at the Harvard Law School cafeteria, on the second floor of Harkness Commons.
CEC meetings are held the second Tuesday of the month from October through May.
