The western black widow is a venomous spider that lives in western North America. The female is black, often with a red hourglass mark on her belly, and her webs are tangled and irregular. Her venom is strong, so it is worth knowing what she looks like.1

It hangs upside down near the centre of its web and waits for insects to land in it. It bites the prey, injects venom, and wraps it in silk. Beetles and ants, wasps and bumblebees make up most of its prey.1

Historical reports gave fatality rates between 0.5% and 12%. However, recent studies have not been able to confirm any deaths from the U.S. species of Latrodectus, including zero deaths among 23,409 documented bites from 2000 through 2008.1

Kikola ki nga kitidde?

Juveniles and females can fling a sticky ball of silk at predators, which can stop most of them.1

Ebituufu

When prey hits a gumfoot thread, the thread breaks and creates tension that pulls the line and prey up to the spider.1

This spider is an opportunistic cannibal, and it may eat other members of its own kind when prey is scarce, when it is very hungry, or in self-defence.1

The silk is strongly sticky, and its strength is similar to that of silk from orb-weaving spiders.1

Males can be preferred by females based on the webs, with well-fed females chosen over starved ones.1

Males may mate several times during their relatively short lives.1
