Plus 3 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 238 verified observations, about 53% of all ticks reported in Delaware. If you spot a tick here, it is statistically most likely to be this one.
Delaware also hosts less common ticks such as Eastern Black-legged Tick and Asian Longhorned 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 Delaware rather than native, so it arrived with human help rather than on its own.
