In February, Entomology Today shared a report from the Journal of Medical Entomology detailing the first-ever appearance of the tick species Haemaphysalis longicornis within North American borders. The tick, native to Asia, was found when an infestation was reported in summer 2017 on a rural property in Hunterdon County, New Jersey.
