Plus 17 more recorded only rarely (fewer than 10 verified sightings). Counts from verified iNaturalist observations.
The Wetland Giant Wolf Spider (Tigrosa helluo) is the most commonly recorded, with 2,167 verified observations, about 45% of all wolf spiders reported in Pennsylvania. If you spot a wolf spider here, it is statistically most likely to be this one.
Pennsylvania also hosts less common wolf spiders such as Dark-legged Pirate Wolf Spider, Ground wolf spider and Forest Wolf Spider, 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. Rustic Wolf Spider is recorded by iNaturalist as introduced in Pennsylvania rather than native, so it arrived with human help rather than on its own.
