Plus 16 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 329 verified observations, about 46% of all wolf spiders reported in Iowa. If you spot a wolf spider here, it is statistically most likely to be this one.
Iowa also hosts less common wolf spiders such as Rabid Wolf Spider, Brush-legged Split Wolf Spider and Carolina 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 Iowa rather than native, so it arrived with human help rather than on its own.
