Counts from verified iNaturalist observations.
The Northern Black Widow (Latrodectus variolus) is the most commonly recorded, with 197 verified observations, about 85% of all black widows reported in Ohio. If you spot a black widow here, it is statistically most likely to be this one.
Ohio also hosts less common black widows such as Southern Black Widow and Brown Widow, 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. Brown Widow is recorded by iNaturalist as introduced in Ohio rather than native, so it arrived with human help rather than on its own.
