An area of particular interest to me is the presence of hidden taxonomic diversity in insects, as exemplified by the carnea group of the green lacewing genus Chrysoperla (family Chrysopidae). One Holarctic morpho-species, Chrysoperla carnea (Stephens), has been shown to be made up of perhaps dozens of cryptic species, isolated by species-specific, substrate-borne vibrational songs. The songs are produced by jerking motions of the insect's abdomen. There is typically no percussive contact with the substrate; instead, the insects "shake" their twigs or leaves upon which they are standing, a phenomenon known as tremulation. In a given song species, the male and female songs are nearly identical. During courtship, the partners will exchange songs more-or-less "politely" in a precise duet, which is a prerequisite for successful copulation.
Examples of the songs of these cryptic species, in oscillograph, sonograph, and sound-clip format, can be experienced by clicking here and then choosing a taxon.

Undergraduate and Graduate Student Advisees (past and present):
Katie Taylor. Katie entered the Ph.D. program in the Fall of 2014. Her interests are in insect behavior, ecology, and evolution -- particularly in factors that influence reproductive isolation and hybridization between incipient or recently-diverged species. She is pursuing both field- and laboratory-oriented tests of specific evolutionary hypotheses, focusing on the widespread carnea-group of cryptic green lacewing species.
Suegene Noh. Suegene entered the Ph.D. program in the Fall of 2003, graduating in December, 2009. She is interested in insect communication and speciation, especially as those relate to acoustical signals. After some initial behavioral investigations of sexual signaling in treehoppers (order Hemiptera), she turned her attention for her Ph.D. project to acoustic preference functions in the European cryptic species of the green lacewing genus Chrysoperla (carneagroup). Since receiving her degree, Suegene has worked in three consecutive postdoctoral positions: first, in Jeremy Marshall's proteomics lab at Kansas State University, investigating prezygotic, postmating reproductive isolation among closely related cricket species; second, in Ted Morgan’s genomics lab at Kansas State, studying the genomics and quantitative genetics of cold tolerance in Drosophila; and most recently, in the Strassmann/Queller lab at Washington University in St. Louis, working on the genomics of cooperation and conflict during the major transition between unicellular and multicellular stages of life of a social amoeba.
Maxi Polihronakis. Maxi entered the Ph.D. program in the Fall of 2002, graduating in May, 2008. For her Ph.D. work, her interests were focused on the behavioral ecology and systematics of the May-June beetles, genus Phyllophagain Scarabaeidae (order Coleoptera). She was (and is) particularly intrigued by the evolution of asymmetrical genitalia in these beetles. Since leaving UConn, Maxi has pursued projects of similar direction and scope with Mike Caterino, at the Santa Barbara Natural History Museum, applying her expertise and creativity to flightless tenebrionid beetles and other coleopterans of the rich California beetle fauna. Maxi then found professional employment working with Dr. Teri Markow at the University of California, San Diego, first as Postdoctoral Project Scientist and later as Assistant Research Scientist in the Drosophila species stock facility. Dr. Markow has recently retired from her Headship position, leaving Maxi in charge of the facility. She is currently also co-PI on a largeNSF facilities grant (funded by the Living Stock Collections for Biological Research program).
Manuel Morales. Manuel completed his Ph.D. degree at UConn in September, 1999. He then took a position for two years as an RTG Postdoctoral Associate in the Department of Ecology and Evolutionary Biology at the University of Maryland, working principally with David Inouye on mutualism. In Fall, 2001, he assumed a full time, tenure-track position as Assistant Professor at Williams College, Williamstown, Massachusetts. He is currently a tenured Professor at Williams.
