Plus 23 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 1,108 verified observations, about 35% of all wolf spiders reported in Illinois. If you spot a wolf spider here, it is statistically most likely to be this one.
Illinois also hosts less common wolf spiders such as Drumming Sword Wolf Spider, Woodland Giant Wolf Spider and Allocosa funerea, 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 Illinois rather than native, so it arrived with human help rather than on its own.
