Female widow spiders are typically dark brown or a shiny black in colour when they are full grown, usually exhibiting a red or orange hourglass on the [[Anatomical terms of location|ventral]] surface (underside) of the abdomen; some may have a pair of red spots or have no marking at all. The male widow spiders often exhibit various red or red and white markings on the [[Anatomical terms of location|dorsal]] surface (upper side) of the abdomen, ranging from a single stripe to bars or spots, and juveniles are often similar to the male pattern. Females of a few species are paler brown and some have no bright markings. The bodies of black widow spiders range from {{cvt|3-10|mm|in}} in size; some females can measure {{cvt|13|mm|in}} in their body length (not including legs).<ref>{{cite web|title=Black Widow Spiders|url=http://www.orkin.com/other/spiders/black-widows/|website=Orkin Pest Control|access-date=19 June 2017}}</ref>  Including legs, female adult black widows generally measure {{cvt|1|-|1.5|in|mm|order=flip}}.<ref>{{Cite web |date=2014-03-01 |title=Black Widow |url=https://kids.nationalgeographic.com/animals/invertebrates/facts/black-widow |access-date=2024-04-01 |website=Animals |language=en}}</ref><ref>{{Cite web |title=Southern Black Widow Spider |url=https://extension.psu.edu/southern-black-widow-spider |access-date=2024-04-01 |website=extension.psu.edu |language=en}}</ref>
