Presenter: Douglas Sponsler

Together, flowering plants and flower-visiting insects make up a third of the Earth’s species. In this talk, we will trace the relationship between flowers and insects from the primordial forests of the Cretaceous to your backyard garden. Along the way, we will discuss the limitations and potential of gardens as pollinator habitat, and we will explore how gardening might be reimagined as a cooperative, landscape-scale practice that could change the ecological meaning of cities and suburbs.

Douglas Sponsler, PhD, was born and raised in Philadelphia, where his love for nature grew out of time spent in urban parks and gardens. He completed his PhD in entomology at Ohio State University, did a postdoc at Penn State University, and is currently a postdoc at the University of Würzburg in Germany. From the fields of Ohio, to the rooftops of Philly, to the Alps of Germany, the theme of his work has been the relationship between flowers, insects, and people.
