Moth Reproduction Topic of Faculty Colloquium at EC
september 28 - 3:15 pm
Eureka College biology professor Mike Toliver will present “It’s in the Bag: Sex Change in the Bushes” at 3:15 p.m. Sept. 28 in the Gammon Room in Melick Library at Eureka College. The free, public presentation is part of the Faculty Colloquium Series.
The presentation will explore findings that Toliver’s biology classes made as they studied the reproduction of bagworms on defoliated versus foliose arborvitae. The sex ratio of bagworms on foliose plants was the expected 50/50, but on heavily defoliated plants it was heavily skewed towards males. Toliver will discuss whether the defoliated environment, with its lack of food, triggers a sex change in the moths or if there is another explanation.
The presentation is the first of five colloquiums by Eureka College faculty members this academic year. Others will be -
“Intellectual Property Rights Regimes and the Choice of Offshoring in the Global Pharmaceutical Market” by assistant professor of economics Codrin Nedita on Oct. 26.
“The Wounded Text: Word and Image in a Fourteenth-Century Codex” by assistant professor of English Jessica Barr on Dec. 7.
“Putting War Widows in Their Place? Mass Death, Mourning, and Memory” by assistant professor of history Erika Quinn on Feb. 1.

All of the presentations will be at 3:15 p.m. in the Gammon Room. For more information, contact colloquiums coordinator Scott Hemmenway at
