Black Widow

Latrodectus mactans


Small glossy black spider with red marking on dorsal and ventral surfaces. Marking on ventral abdomen is usually in the shape of an hourglass.


The black widow spider prefers dark, undisturbed areas such as deep insider closets or garage corners. This individual was found under the toilet lid of a long-abandoned campsite.


The black widow is one of two spiders of medical significance in Oklahoma. Its venom is neurotoxic, though rarely fatal.

Such a clear photo. They are so like the Aussie redback (to which they are related) - but the "black widow" name alone sends chills down the spine!

When I was a kid, the local natural history museum had a collection of live animals, including a black widow tank, which they'd put a toilet seat in. They said that black widows loved using toilet seats to make webs, and for years after, even though we lived too far north in Canada to get them, I always checked under the toilet seat for any rogues! I laughed a little when you said you found this guy under a toilet seat :) Beautiful picture, well done on getting that close haha!
