The public is invited to attend the May meeting of the Cambridge Entomological Club on Tuesday, May 8 at 7:30 pm at Harvard University, 26 Oxford Street, MCZ 101 in Cambridge. Profesor Douglas J. Futuyma of Stony Brook University, Department of Ecology and Evolution, will discuss Herbivorous Insects: Studies in the Evolution of Diversity. Questions about coevolution, ecological specialization, speciation, evolutionary rates, and diversity apply to many or most organisms, but are dramatically exemplified by herbivorous insects, which together with their host plants account for nearly half the described species of living organisms. Professor Futuyma will recount highlights of field and laboratory studies that he and his students have pursued in trying to answer some of these questions, and he will offer some tentative answers, while yet emphasizing that puzzling problems remain.
