Current Projects

• Development of online keys, checklists, and information on North American delphacid planthoppers, including potentially invasive species.
• Higher systematics of the delphacid planthoppers (Hemiptera: Delphacidae) of the world (with Jason Cryan and Julie Urban, New York State Museum).
• Auchenorrhyncha of the Great Smoky Mountain National Park (supported by Discover Life in America and National Park Service).
• Keys to genera, with species checklist (including synonyms), for planthoppers north of Mexico, with particular emphasis on western USA (with Lois O’Brien & Steve Wilson).
• Recently completed is an inventory and keys to planthoppers of Delaware (62 species, excluding Delphacidae). Soon will be Delphacidae of Delaware.
• Revision of select delphacid genera and descriptions of new species. Work is in progress revising the genera Tetrasteira (with Lawrence Barringer), Chionomus (with Katie Weglarz), Caenodelphax (with Ashley Kennedy) and a new genus segregated from Delphacodes.
