Sam Droege is the head of the USGS Native Bee Inventory and Monitoring Program in Maryland, an organization that monitors the health and habitat of bees in the U.S. as well as creating archival reference catalogs that aid researchers in the identification of bee species in North America. The project is no small task as there are literally thousands of bee species in the U.S., some of which vary in only the most minute ways that may not even be distinguishable to the naked eye.
