The NJ Department of Agriculture gave a news release about the exotic tick, Haemophysalis longicordis and it’s discovery in a new location in Union County: http://www.state.nj.us/agriculture/news/press/2018/approved/press180425.html
This place in Union County is about 40 miles from the Hunterdon location, originally thought to be the first location for this invasive tick. But samples from the Union site were collected by James Occi in May of 2017, prior to the Hunterdon discovery. Upon reconsideration, these tiny nymphs were genetically determined to be the exotic old world tick and not the native Haemophysalis rabbit tick as originally thought. Stay tuned for more developments!
