What Does a Black Widow Spider Look Like?
- Female black widow spiders have red hourglass markings on the side of the abdomen that typically faces the ground. Otherwise, their bodies are entirely shiny black.
- Male black widow spiders are easily distinguished from the venomous females. They have different markings from females, with red and yellow bands and spots on their backs. The male black widow spider also has longer legs and bodies that are half as long.
- Juvenile black widow spiders look just like the males.
How Common Are Black Widows?
Most people in North America will go their entire lives without ever seeing a black widow spider. These spiders are primarily found in warmer climates. People living in the American Southwest are more likely to see them than people living in Northeast America, for instance. As a general rule, people will be more likely to see black widow spiders at a latitude of 45 degrees North and South.
Can You Die from a Black Widow Spider Bite?
The good news is that people actually rarely die after being bitten by female black widow spiders. In fact, the human mortality rate from black widow spiders is less than one percent. The spiders will only inject a relatively small quantity of poison during a particular bite. This is more than enough poison to kill an insect, which is what a black widow spider will eat. Black widow spiders will rarely encounter animals as large as humans in the wild, and large animals are much more likely to withstand toxins that will kill smaller animals. People certainly don't have to live in fear of black widows.

What Do I Do If I’m Bitten by a Black Widow?
Washing the bite, applying an antibiotic cream, and then applying an ice pack to the wound can really help in the meantime. However, these are not the ultimate solutions to the problem. If you suspect that you’ve been bitten by a black widow spider, you should still go to the emergency room. If possible, someone should try to capture and save the original spider for the sake of identification. However, this is somewhat risky, so people should be careful about this step.
Do Male Black Widows and Juvenile Black Widow Spiders Bite?
Male black widow spiders and juvenile black widow spiders are harmless to humans. It is possible that they might bite defensively, but it's unlikely. If they did bite, it would not be dangerous. Male black widow spiders and juvenile black widow spiders do not tend to be aggressive, and they are much more likely to avoid humans, so this is not something that people should generally fear.
The Black Widow Life Cycle & the Juvenile Black Widow
Mating season for black widows, like most animals, is in spring and early summer. Black widows can produce hundreds of eggs in one egg sac and multiple egg sacs per mating season. These egg sacs stay tightly woven in the web until they hatch.
Juvenile black widows tend to eat their siblings after hatching, meaning only a handful survive from each egg sac. As time goes on, the juvenile black widow will spin its own web to grow and stay alive during winter.
Black widow spiders can live 1-3 years but are usually closer to one.
