What is the black widow spider?

The black widow spider is one of the most common and most menacingly named of all spiders. These black, yellow, and red-marked arachnids are also known as Loxosceles or Southern Black Widow Spider in some parts of the world.

There are eight common species in North America, and they are Euticea coccinea, Latrodectus mactans, L. geometricus, L. variolus, Steatoda triangulosa, S. Nigricans, S. Vinivacta, and SteatodaGNU? aetutatiora.

They are large spiders that can grow up to four inches long (including the abdomen) with the female having a leg span that can be as much as two inches across at maturity.

These venomous arachnids are active hunters that use their strong jaws and fangs to capture their prey in agonizing bites to the legs and body areas of their victims. The male black widow spiders are solitary creatures that live under rocks and logs but will hunt for females when mating season arrives.

There are two types of female black widow spiders: huntresses and sitters. Huntresses will track an unsuspecting victim and bite it on contact while sitters wait for a victim to come into close range before striking it with their fangs and injecting their venom with a neurotoxin that paralyzes their prey before they drink the blood.

The bite sites look like small puncture wounds and can be fatal if not treated right away with antivenom serum or fluids as directed by a medical professional.

What are the dangers of black widow spider bites?

There are many dangers associated with black widow spider bites. The most common one is the pain of the bite itself and the development of a small or large developing welt.

Also very rarely, the bites of a black widow can cause Hemaphagema. This is when blood vessels in your mouth fill with blood and it becomes painful to drink or eat.

If this happens, it will improve without treatment within 24 hours if you rest and apply ice to it, but if untreated it can lead to more serious problems such as damage to internal organs or loss of eyesight as can happen in Glaucoma.

Lastly, the bites of a black widow spider can lead to death in certain cases. This always happens after large generalized varicelliform lesions develop indicating severe systemic toxicity.

In this type of case, death usually starts with shock due to circulatory failure that follows after the development of large bloody skin ulcers on areas such as hands or feet due to massive tissue destruction by antibodies.

None of these are good signs from an acute infection standpoint so I would consider any one of these symptoms potentially life-threatening despite being rare.
