Mississippi has a broad diversity of animals, including some of the most dangerous spiders in the United States. While many spiders help to decrease bug populations, homeowners and visitors must distinguish the rare species that pose a serious hazard.
Understanding these spiders can help to avoid risky encounters and ensure safety. In this article, we will look at the four most venomous spiders found in Mississippi, including their characteristics, habitats, and potential concerns.
Whether you’re an outdoor enthusiast or simply curious about local animals, this information will help you navigate the spider-infested landscapes of the Magnolia State with ease.
1. Brown Recluse
The brown recluse spider is commonly found in North America. While these spiders are most commonly found in Nebraska, Texas, Iowa, and Ohio, Mississippi also has a large population of them. The brown recluse spider, as the name implies, is brown throughout, except for a violin marking on its cephalothorax. It can reach a size of one inch and, unlike most spiders, has six eyes rather than eight.
Brown recluse spiders prefer to build their webs in isolated spaces such as barns, closets, and even cardboard inside homes. Because of this, human interaction is widespread, which can occasionally result in bites. This spider’s necrotic venom causes symptoms such as necrosis, discomfort, vomiting, and, in rare cases, hemolysis (blood clots).
If bitten, seek emergency medical attention, especially if the victim is a youngster. Fortunately, brown recluses are considered to be very cautious and will avoid biting humans. A remarkable example was in 2001 when 2,000 of these spiders were removed from a residence, but none of the four homeowners were bitten.
2. Brown Widow
While its name begins with the same word as the brown recluse, the brown widow is a distinct species of widow spider. It is a cousin of the well-known black widow and is endemic to Africa. Over time, the spider has spread to new countries like as India, Poland, Australia, and the United States.
Today, it is one of Mississippi’s four venomous spider species, distinguished by black and white abdominal markings on a tan to dark brown body. This spider also has an orange-to-yellow hourglass pattern on its abdomen and conspicuous black stripes on its legs. Adult brown widow spiders can grow to be 1.5 inches long when their legs are fully extended.
As a tropical species, the brown widow prefers outdoor habitats such as tree stumps, woodpiles, and rocks. This minimizes the likelihood of human interactions, resulting in less touch and fewer bites. Even if bitten, the brown widow’s neurotoxic venom is not deadly. At most, a bite will cause numbness and pain near the location. Unless you detect any other symptoms, hospitalization is usually not required following a brown widow bite.
3. Southern Black Widow
Mississippi’s deadly spiders include the well-known southern black widow. This species belongs to the widow spider family and is native to North America, particularly in the southeastern United States. This spider’s body is lustrous black, except for the underside of its abdomen.
The black widow bears a vivid red hourglass marking, which is its primary distinguishing feature. Southern black widows are small, with an average length of 0.3 to 0.5 inches, or less than a penny.
Southern black widow spider bites are rarely lethal, despite being portrayed as one of the world’s most poisonous species. To begin, only adult females possess chelicerae (venom-injecting fangs) long enough to inject poison into humans.
The death rate from these spider bites is less than 1%. Most bites to healthy people will merely result in symptoms like pain, hypertension, perspiration, edema, and numbness. Quick medical intervention and the availability of antivenom lessen the possibility of serious symptoms.
4. Northern Black Widow
The northern black widow, a near cousin of the southern black widow, is another species of widow spider found in Mississippi. Northern black widows live largely in the Middle Atlantic states, but they can also be found in southern Canada and Wisconsin. They resemble the southern black widow in appearance, with a black hue and a red hourglass marking on the back.
However, unlike its cousin, the red hourglass on a northern black widow has a huge gap in the center, commonly known as a “broken hourglass.” The spider has reddish-orange markings on the top of its abdomen that become more pronounced as it matures.
A northern black widow bite should be treated as soon as possible because it can cause a variety of symptoms. One of the most common is latrodectism, a bite-related disorder that causes muscle rigidity, discomfort, swelling, and other symptoms.
Additionally, local redness, nausea, and vomiting can continue for up to a week following a bite. Fortunately, bites are rarely lethal, and the northern black widow spider will not bite unless provoked.
Conclusion
In conclusion, while Mississippi has a varied range of spider species, understanding the four most dangerous types—brown recluse, brown widow, southern black widow, and northern black widow—is critical for safety. Understanding their traits and behaviors can help to reduce interactions and provide a safer outdoor experience. Remember that immediate medical assistance following a bite is critical for effective treatment, while serious results are uncommon. Stay aware and watchful to fully appreciate Mississippi’s natural beauty.
