Habitat

Synanthropic, may occur in undisturbed natural habitats in US range as well.

Webs primarily above ground, underside of tables, chairs, awnings, rooftops, etc. Often found in old, abandoned webs of Latrodectus geometricus and Kukulcania hibernalis.

Sympatric with L. geometricus, K. hibernalis, and likely other synanthropic spiders throughout its range.

Mature females often cohabitate with one or more males, and offspring may remain in parent web for several instars.

Despite social behavior, cannibalism does occur, often between battling males.
