President’s Address: Mechanisms of a Neotropical coevolution: plant-insect communication in a cycad-weevil symbiosis

Pollination mutualisms are well known, even kindergarteners know that the bee and the flower both benefit. Obligate pollination symbioses where both partners completely rely on the other for lifecycle completion, however, are represented by only a handful of examples: the fig-fig wasp and yucca-yucca moth mutualisms being the most famous. In this talk, I will introduce you to another obligate pollination symbiosis; one unique in that it involves a non-flowering plant. We will discuss the symbiotic relationship of the gymnosperm cycad genus Zamia and their Rhopalotria weevil partners and ask what mechanisms exist to maintain this specialized relationship and if we can see evidence of co-evolution in these groups.
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 5:45 PM) at the West Side Lounge, 1680 Massachussetts Avenue, Cambridge.
CEC meetings are held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (5:45 to 7:15 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.

Sonic the Caterpillar and Other Insects Unheard Of

We are all familiar with insect sounds, particularly those used for advertisement over long distances, such as the familiar chirps of crickets or buzzing of cicadas. Over the past 60 years acoustic communication in arthropods has been researched extensively, yet despite this plethora of research, the vast majority of reports focus on airborne sounds of adults. What many do not realize is that insects generate and detect an extraordinary diversity of acoustic (sound and vibration) signals that extend far beyond human sensory capabilities. Moreover, we are only beginning to understand how larval insects such as caterpillars are communicating acoustically. In my laboratory we employ specialized instruments to tap into these secret communication channels. My presentation will explore the diversity, function, and evolution of acoustic communication in caterpillars. I will focus on three models developed in my laboratory over the past several years: Defensive sounds in silk and hawk moth caterpillars, vibratory ‘rap battles’ in hooktip moth caterpillars, and ‘hearing’ in monarch butterfly caterpillars. The complex acoustic landscape of insects and other invertebrates remains unchartered territory ripe for further exploration!
