Where Do Black Widows Actually Live in the US?
Black Widows have confirmed sightings in 45 US states, based on 41,164 verified occurrence records.
By Tim, founder of Easy Street Markets. I maintain the wildlife database and verify every animal and source myself.
The states with the strongest confirmed populations are Alabama, Arizona, Arkansas, California, Colorado and Connecticut, and 39 more. These are real, verified iNaturalist and GBIF occurrence records, not modeled range estimates.
A small number of states (4) have only a handful of unverified or vagrant records, too few to confirm black widows as an established population there.
