- Red hourglass marking. Check for 1–2 red triangles on the bottom of the spider’s body. The triangles are on the bottom of the spider’s backside, also known as its abdomen, so they'll be visible when the spider is hanging from a web but harder to see if it's crawling around.
- Shiny black bodies for females. Females are seen most often and they have hairless, dark bodies. Female black widows are dark-colored and have smooth, shiny bodies that grow up to 1⁄2 in (13 mm) long, excluding the legs.
- Tan body for males and juveniles. Look for white and tan patterns on these lesser-seen spiders. Young spiders and males have reddish-brown legs and a splotchy white abdomen.
