Seminal influences: The role of male ejaculates in firefly evolution

MCZ 101, 26 Oxford Street, Harvard University

Adam South, Tufts University

Have you ever wondered what is behind the flashing lights of fireflies? Adam South will discuss his fascinating research exploring firefly mating, sexual selection and nuptial gifts. Male fireflies produce and transfer to the female a proteinacous, spirally coiled spermatophore each time they mate. These types of seminal nuptial gifts have been shown to be intimately connected with pre and post copulatory sexual selection in a diverse array of taxa. This presentation will examine spermatophore production from a phylogenetic perspective, including how it is linked to sex specific patterns of evolution and its role in firefly sexual selection.

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. The evening schedule typically includes an informal dinner (6:15 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.

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.
