Counts from verified iNaturalist observations.
The Brown Widow (Latrodectus geometricus) is the most commonly recorded, with 30 verified observations, about 71% of all black widows reported in Hawaii. If you spot a black widow here, it is statistically most likely to be this one.
Hawaii also hosts less common black widows such as Brown Widow and Western Black 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 Hawaii rather than native, so it arrived with human help rather than on its own.
