This spider’s bite can kill you.

The violinist spider, also called “corner” or “brown”, is characterized by having a brown spot in the shape of a violin on the cephalothorax

Along with the black widow, it is one of the most feared spiders and, without proper attention, can cause death.

That’s all you need to know about the fiddler spider.


Found in both urban and rural spaces, they are not aggressive and usually bite when disturbed in their habitat.

They weave a messy, loose, white cloth where they live and devour their food.


In the bedroom, they are behind furniture, pictures and especially inside the closet. They prefer dark, damp, and poorly ventilated places such as sheds, lumberyards, basements, and attics.

Life cycle

The male fertilizes the female, which spawns small eggs of irregular size inside the ootheca (small silky sacs).

Each of them contains from 30 to 140 eggs distributed on the web. The female guards the eggs until death and is capable of laying up to 300 eggs during her lifetime.

Chicks emerge from the egg between 24 and 36 days. It presents a slow development that can take from 10 to 12 months depending on the sex, feeding conditions and environment.

They live an average of two years and are very hardy as they can survive long periods of time without food or water.


As we mentioned before, they tend to attack when they are disturbed in their habitat. The amount of venom it injects depends on the size and gender of the spider, the bigger it is, the more venom it deposits, as if it were a female.

Initially, the bite is painless, but hours later, the individual feels itching and pain at the injury site.

In the first 72 hours, the patient may experience fever, chills, headache, nausea, vomiting, muscle and joint pain and red spots on the skin as a reaction.

In the following days, the site of the bite changes. Deep purple sores or blisters appear on the skin, causing necrosis, destruction of red blood cells and, depending on the amount of venom, death.

Experts mention that the definitive sign that it is a violinist spider bite is that a red wound is created surrounded by a blue-white ring like a “bull’s eye”.


It is very important that if you notice any of these symptoms or skin changes, go immediately to the nearest Health Center to receive the antidote and treatment.
