Marty Condon, Dean C. Adams, Darrin Bann ('06), Kacie Flaherty, John Gammons, Jessica Johnson, Matthew L. Lewis, Sara Marsteller, Sonja J. Scheffer, Francisco Serna, and Susan Swensen. 2008.  Uncovering tropical diversity: six sympatric cryptic species of Blepharoneura (Diptera: Tephritidae) in flowers of Gurania spinulosa (Cucurbitaceae) in eastern Ecuador. Biological Journal of the Linnean Society 93: 779-797.

The article describes the diversity found in plant-eating flies in Ecuador.  The research was supported by an NSF grant to Swensen and her collaborator, Marty Condon (Cornell College, Iowa).  Several IC undergrads also participated in the research: Robin Rakobitsch (Biology '05), Anthony Santoriello (Biology '05) and Leslie Adams (Biology '05).  View the PDF of the abstract here.  Read Ithaca College's story here.
