Key Points:

  • Black widows kill more small snakes than any other spider.
  • Black widows will kill small young snakes that get stuck in their web.
  • Although black widows can kill snakes, their venom is rarely fatal to humans.

Black widow spiders have a deadly reputation. Their scientific name is Latrodectus which comes from the latin word “latro,” meaning “bandit,” and the Ancient Greek word “dēktēs,” which means biter.

So, their name translates as “bandit who bites!” The name black widow comes from the fact that females sometimes eat males after mating.

This unique footage was recorded in Texas and shows the moment when a black widow spider captured a snake in its web. Yes, a snake!

Black Widow Spiders Are Amazing

However you feel about spiders, and some people like them more than others, you cannot help but be impressed by the black widow spider. On the face of it, they don’t look that special.

The female black widow is around 1.5 inches long and the male is half that. The females are a shiny black color, with a red-orange hourglass pattern on their abdomen. The males are brown or gray with small red spots.

However, these spiders have populated most of the world, they have venom that is strong enough to kill a dog and spin webs as strong as steel.

So, let’s look at that in a little more detail.

What Do Black Widows Eat - Black Widow with Prey

Black widows use their venom to defend themselves and to subdue and consume prey (such as flies, ants, and grasshoppers) as this snake is, unfortunately, finding out! The venom contains an alpha-larotoxin which is powerful – 15 times stronger than a rattlesnake. But because they are so small, they only deliver a small amount and so it is rarely fatal for humans.

It is very unpleasant though! It causes swelling and a lot of pain and medical attention is needed. Only adult females will bite you – the males’ mouthparts are not strong enough to do so. Black widows kill more snakes than any other type of spider and they typically target small, young snakes that have gotten stuck in their webs.

Black widow webs are awesome! The web silk is several times stronger than that spun by other spiders. It is the same durability as Kevlar which is a synthetic fiber used to make bulletproof vests! Their cobweb is made up of support scaffolding in the middle and a series of silk anchor lines that hang down. There are two types of silk used in the web and one will stretch 25% of its length before breaking!
