Plus 1 more recorded only rarely (fewer than 10 verified sightings). Counts from verified iNaturalist observations.

The Lone Star Tick (Amblyomma americanum) is the most commonly recorded, with 1,234 verified observations, about 43% of all ticks reported in New Jersey. If you spot a tick here, it is statistically most likely to be this one.

New Jersey also hosts less common ticks such as Asian Longhorned Tick and Gulf Coast Tick, each recorded fewer than 100 times. These are the species worth a second look when you are out, since a sighting is more notable.

Not every one of these is originally from here. Asian Longhorned Tick is recorded by iNaturalist as introduced in New Jersey rather than native, so it arrived with human help rather than on its own.
