Hello, Friends, Do you know about Black widow Spider? If you do not know about this deadly spider, then I am going to tell you about a fatal spider who found in North America. But these spiders drastically increasing in Europe and Asia. The spider is considered the most venomous spider on the earth; their cure is not natural. Sometimes patients die from the bites of this spider.

What is Black Widow Spider?

Latrodectus, commonly known as Black Widow Spider is the most deadly spider found in temperate regions all over the world. it belongs to a group of spiders commonly known as cobweb spiders.

It is very common to find this spiders in dark and dry areas of United States, Australia, and South of Europe, Asia, and Africa.

In the US, you can find at least one species of this spiders in every state, except Alaska. However, dangerous weather conditions such as excessive cold or drought may lead these spiders towards residential colonies.

These widow spiders are found in regular places like wood piles, outhouses, underneath debris. The web is usually near the ground.

What about their life, and behaviour?

Almost all species of black widow spider have the same body structure. Mouthparts of both- northern and western spider are chelicerae and fangs, which are perpendicular to its body line.

Mouth and jaws are on the underside of the head of these spiders. They all have eight eyes and eight long, narrow legs. They lay eggs in clusters and have an egg sac made up of silk.

Differentiating in between male and female spider is natural. Female ones have red hourglass body-shape with a dark shine of size approximately 1.5 inches.

Whereas, he has a flat body with pink or red spots all over them and is half of the size of female spiders. Also, that red colour in female spiders may also be orangish-yellow, depending upon various external factors.

These carnivores’ spiders weigh about 0.035 oz. He’s lived for about 1-3 years. In general, re-quite calm and non-attacking as they like to stay hidden in their web, they only bite in their defence. Do note that just

Do note that only female is venomous; male spiders do not eat. Their web is also ill-woven as they are rough and sticky, though the silk is stronger as compared to that of other arachnids.

 Life Cycle And Hunting

He made from springs to early or mid-summer. They are known for their mating style as many times female black widow spider kills and eats her partner male spider to provide nutrition to self, which is essential to get the eggs fertilised. It is stated that many times

It is said that many times female spider puts her eggs in the dead male spider and protect them until the time they hatch. Eggs of these spiders have a texture of the paper and are of 6-7mm in radius.

They are roughly oval spherical, and from each sac hundreds of spiderlings take birth. But only a few of them can survive because black spiders are anthropophagical in the early stage of their lives and consume fellow spiderlings for the sake of nutrition.

Difference Between Male V/S Female Black Widow Spider

Young spider or spiderlings are usually white or off-white and gradually get more varying shades of red and black. In addition to that, they do not harm human beings.

Within some days of hatching, these young spiders go through the process of ballooning. Ballooning is the process in which

Ballooning is the process in which spider release silk into the air and this way they are carried to different locations via air.

After this, these spiders weave their nests and start hunting food for themselves. Just like most of the spiders, the black widow spiders too, eat insects that get themselves caught in the nest.

They do eat flies, mosquitoes, small insects, and caterpillars. Female widow waits for the prey while hanging upside down from her nest.

In this position, the female spider gives a warning to predators that she is a harmful organism and intent to keep them away from her nest. But as reported by The Society for Integrative and Comparative Biology, this technique of

But as published by The Society for Integrative and Comparative Biology, this method of spider does not work a lot because of the difference in between colour-perceiving capacities of birds and insects.

As the prey is trapped in the nest, black widow spider wraps it in silk using their ‘comb feet.’ After that, these spiders lock the victim and liquefy the body of prey using individual enzymes to suck the fluid out of it.

Bite, Precaution, And Cure

The venom of black widow spiders is said to be 15 times stronger than that of a rattlesnake. It means, it is highly poisonous.

But, as mentioned earlier, only female widow spiders bite is considered as a threat to human health. The venom of the black widow spider is a neurotoxin, and it alters the structure and function of nerve terminals.However, do not produce any significant local reaction.

In starting spider’s venom gives a sensation of a pinprick and notch and then starts spreading all over victim’s body. But as a matter of fact, the bites of Latrodectus is not reported to be life-threatening. From last ten years the US, no one has died because of widow spider’s venomous bite.

For most of the victims, widow’s bite results into issues like nausea, sweating, severe body pain, Eyelid swelling, Dizziness, Sore muscles, high blood pressure, difficulty in breathing and paralysis of the diaphragm.

You can quickly recognise widow bite if the victim has symptoms. With proper medications and black widow antivenom, pain can be cured in 8-12 hours.

But, other effects of black widow’s venom in the body can last for several days. However, sometimes their bite results in significant issues for people with little immune power- infants, aged or weak.

As first aid measure, the bite location should be washed with soap and water. After that ice- pack should be placed over it.

Difference Between Northern And Western widow Spider

The Northern Black Widow Spider, scientifically named as Latrodectus variolous can be found everywhere in the eastern US  from southern Canada south to Florida, and west to east Texas, Oklahoma, and Kansas.

He is a more common sight in Michigan than in western Lower Peninsula. On the other hand, Western Black widow spiders live in western areas of  North America. From Mexico to southwestern Canada (British Columbia and Saskatchewan), and the United States (Arizona, Texas, and California).

Due to the mere presence of western spiders in the US,.Araneophobia, or irrational fear of spiders, is common among people in the United States.

Also, females are found to be less likely to eat their male partners after mating. In addition to that,

In addition to that, male western spiders choose their mating partner by determining if the female spider has already eaten or not. They ensure this by sensing enzymes in the nest of a black female widow.

There are five species of western spiders in North America, north of Mexico.

  • Latrodectus Hesperus, Western black widow spider ( western Texas, Oklahoma, and Kansas north to Canada and west to the Pacific Coast States)
  • The Latrodectus mactans (Southern New England to Florida west to eastern Oklahoma, Texas, and Kansas)
  • Red-legged widow (southern Florida), Latrodectus bishops
  • The Latrodectus geometrics, Brown widow (cosmopolitan)
  • Latrodectus variolous, (New England and Canada south to Florida and west to eastern Texas, Oklahoma, and Kansas)
