With a little bit of training, 59 citizen scientists in New York collected more than 3,700 ticks across 15 counties in a two-week period in the summer of 2021, greatly expanding the reach of professional tick researchers at the Northeast Regional Center for Excellence in Vector-Borne Diseases. Among the tick specimens the volunteers found, most were Asian longhorned ticks (Haemaphysalis longicornis, 54 percent of specimens). (Photo by danbarb via iNaturalist, CC BY-NC 4.0)
