Description

When you study spider species, it is important to know about how to identify them or how they appear to be. Once you know how they look, you will be able to identify them easily and get yourself away from them also. The brown widow spider has a coloration of tan and brown, along with a black accent marking. The black accent marking, varies from gender to gender in the brown widow spider. The females or mature females have a longitude stomach stripe and three oblique stripes present on the flank. Each oblique stripe has a black mark on it, which looks quite square-ish.

The Brown Widow spider also has an hourglass, but unlike the black widow’s vivid red one, its hourglass is of an orange shade. The Latrodectus Geometricus resembles the immatures of the western black widow spiders sometimes. It gets tough sometimes to actually differentiate the immature black widow spiders from the brown widow ones but someone with perfect knowledge will certainly get ahold of the differences. It just simply demands a lot of experience and obviously information at hand.

The most diagnostic feature of a brown widow spider is its egg sac. The egg sacs which are not attached to the flat surfaces are better known as free egg sacs. These resemble a lemon drop candy or a small cotton ball, but both these have inaudible edges. A brown widow spider’s egg sac has a lot of silk spicules coming out of its surface. It is mostly said that the egg sac of the brown widow spider looks more like a large pollen grain. Some have said that it looks like a harbor mine that has been created just perfectly to blow up ships. The egg sac of this spider is so unique that it can be easily recognized. Yet again, someone with immense information won’t find it hard to recognize the egg sac at once, but if you are trying to figure it out for the first time, you might have to go a bit crazy for it.

Reproduction

Brown widow spiders are able to produce a lot of egg sacs in their entire lifetime. That is why they are termed as prolific breeders. It is also said that they lay multiple egg sacs in only one sequence. They have almost 120-150 eggs per sac. Moreover, they are able to create 20 egg sacs in their complete lifetime cycle. Now if we compare it with the black widow spider, then the brown widow spider lays the same amount of egg sacs. Black widow lays 300 eggs per sac, but can only produce 10 egg sacs in their entire lifetime. Yes, you can do the remaining math on your own.

Mating

Male and female brown widow Mating or sexual cannibalism in brown widow spiders is actually known to be a process that reflects the commitment of male spiders the most. It is also known as the extreme form of male monogamy. According to the researches, male brown widow spiders achieve reproductive success by forfeiting themselves to the female spiders.

It is also said that male spiders attempt the mating process with somersaults or virgins mostly. The females, who have been previously mated with, have less chances of sexual cannibalism again. Studies found out that the mating process in brown widow spiders are frequent. How do the two mate? The male spider places his abdomen in front of the female’s mouth parts for the mating process.

The studies however, show that the mating process is a total male strategy in the brown widow spiders. The self-sacrifice is not known to be taken place in this species before or not.

Habitat

Brown widow spider in web

Brown widow spiders usually build their protected sites in wooden vegetation, which have branches. They can also build their webs around homes. There are some typical places in which brown widow spiders tend to make their webs in. They usually build them in empty buckets, containers, mailboxes, garbage cans, undersides of outdoor furniture, wrought iron railings, storage closets, under eaves, etc. The places that brown widow spiders choose are risky; why? These are those places where they can bite on humans quite easily. That is why it is always safer to keep such stuff checked and cleaned in all ways that you can, otherwise it can be harmful for you or your family. It is also preferred that the outside of your home is checked on and cleaned once or twice a month to avoid interactions with such spider species.

Spider bites

Yes, a brown widow spider bite can be bad, but if it is compared to that of a black widow spider, then you might just find out that it is minor in front of that one. A black widow spider bite is quite major compared a brown widow’s one. As mentioned above, a black widow spider bite is the most feared spider bite. Even when the male black widow spider is said to be less venomous, the female is feared the most. It can paralyze a human as well; the latest news showed this fact!

However, coming back to the brown widow spider, studies show that the venom of a brown widow spider, drop by drop, is quite toxic. It is also said that it is equally toxic as other widow species, so it cannot be confirmed that a black widow spider bite is more harmful than a brown one. The toxicity of venom is the major aspect which tells you about the potential of the spider bite in all.

A recent study however, confirmed the fact that the bite of a brown widow spider is minor; how? It is due to the fact that the brown widow spider cannot inject a lot of venom into the humans, as compared to its other relative species. A black widow spider has the potential to inject in a lot of venom into the human body.

There were basically two signs that were found out after a brown widow spider bit a human. First, there was irritation in the bite area. Second, a red mark was left in the injected area. These two signs are quite similar to the ones that are experienced from the bite of a normal spider in all. However, recent news came up that a man had to be hospitalized when bit by a brown widow spider, so as mentioned above, there is nothing that confirms what the bite can bring to you, as the venom in all is toxic. It all depends on the amount of venom which gets injected in you, within a bite. It is also reported that brown widow spiders are taking over quite rapidly and are becoming somewhat similar to the black widow spiders. There just may be some shift in the species composition overall.

First aid

You always need to have a first aid box in your bag, at your home, office and car. It is important as you don’t know when an emergency occurs and you certainly cannot wait to reach home and clean your wound. Safety comes first, remember?

First aid

Now how can you take care of a spider bite? This first aid is not specifically for brown widow spider bites, as the signs of their bite are completely similar to normal bites. Therefore, whenever a spider bites you, you can follow these easy first aid steps. Visit the doctor as well as soon as possible. Sometimes the venom injected is more and you can experience nausea, headaches, muscle weakness and contractions. Now if you do experience such symptoms, it is always better to visit the nearest doctor for your first aid. Here is how you can take care of a brown widow spider bite:

  • Clean the infected area. You can utilize a mild soap or water and then apply an antibiotic cream on it.

  • Apply a cool compress to the wound after cleaning it. You can damp a cloth in water, preferably cold water to compress the wound with it; why so? This reduces the swelling and pain caused by the bite. If the bite is on your leg or arm, you need to uplift it.

  • Ibuprofen If you still feel the pain, it is better to visit a doctor so that he/she can give you an over the counter medicine. In minor bites, over counter medication remains best. There are several pain relievers but it is always best to take the one which your doctor prescribes you. If you cannot visit the doctor, you can try taking Ibuprofen (Motrin IB) or take an antihistamine (that is Benadryl, Chlor-Trimeton).

  • A lot of people might ask when it is really important to visit the doctor. Well, if you are unsure of the type of spider that bit you, then it is best to visit the doctor, but if you know that it was a normal spider or a brown widow one and it did not get enough time to bite you properly, then it is okay to handle it yourself.

    Secondly, if you are sure that it wasn’t a big bite, but your pain is still not relieved and you feel nausea or muscle pain, then it is time for you to visit the doctor. In severe cases, a person who got bit and cannot breathe must be taken to the hospital right away.
