Louisiana may conjure up images of bayous, moss, and alligators, but it is also home to a few scorpion species. Fortunately, there are only three types of scorpions found in the state, and some are more dangerous than others. The Striped Bark Scorpion, with its black stripes and slender pedipalps, is relatively harmless to humans, while the Southern Devil Scorpion, with its tropical climate preference, can deliver a more potent sting. Lastly, the Pseudoscorpion, though not a true scorpion, bears a striking resemblance and is completely harmless. Overall, Louisiana residents can rest easy knowing that there are no truly dangerous scorpions in their state.
1. Striped Bark Scorpion
Scientific Name: Centruroides vittatus
The Striped Bark Scorpion, scientifically known as Centruroides vittatus, is a species of scorpion found in Louisiana. This scorpion can grow up to 60 millimeters, or 2 ⅜ inches in length, including the tail. The tail is shorter in females than in males of this species. The Striped Bark Scorpion typically ranges from yellowish to tan and features black stripes on the top of the abdomen. Some members of this species are only faintly marked and may be paler in color. The head of a scorpion is called the carapace, and you may notice a black triangular mark above the eyes of this species. All scorpions have a pair of pedipalps, which are the second pair of appendages they possess. Some may consider these to be claws, but many arthropods have them, including spiders, horseshoe crabs, and sea spiders. The Striped Bark Scorpion has a slender pair of pedipalps, making it easier to identify.
When it comes to its sting and venom, the Striped Bark Scorpion’s sting may hurt, turn red, and swell, but it is not lethal to humans unless an allergy is present. It is important to exercise caution when in the presence of these scorpions and to seek medical attention if stung and experiencing severe symptoms.
2. Southern Devil Scorpion
Scientific Name: Vaejovis carolinianus
The Southern Devil Scorpion, scientifically known as Vaejovis carolinianus, is another scorpion species found in Louisiana. Also known as the Southern Unstriped Scorpion, this species is a common resident in the state. Unlike the Striped Bark Scorpion, the Southern Devil Scorpion prefers a more tropical climate, which explains its presence in Louisiana’s hot and humid environment.
When it comes to description and identification, the Southern Devil Scorpion is similar to other scorpions. It has a pair of pedipalps, elongated body, and eight legs. The Southern Devil Scorpion is nocturnal, choosing to be more active and hunt for food at night. To avoid encounters with these scorpions, it is advisable to shake out camping equipment and check shoes in the morning. While their sting is not dangerous to humans, it can cause redness, swelling, and pain in the affected area. Medical attention may be necessary if these symptoms persist.
Mating and reproduction play an important role in the Southern Devil Scorpion’s life cycle. Males and females engage in a courting process that involves clashing their claws together and performing a special dance. After mating, the female can give birth to up to 80 live offspring. The babies ride on their mother’s back until they are ready to live on their own.
Scientific Name: Pseudoscorpionida
The Pseudoscorpion, scientifically known as Pseudoscorpionida, is an arachnid species commonly found in Louisiana. Although they may resemble scorpions, they are not true scorpions. Pseudoscorpions have elongated pincers and eight legs, which often lead to confusion with scorpions. However, they lack a tail and stinger, making them harmless to humans.
Pseudoscorpions have a reddish-brown color and can grow up to ⅜ of an inch when their pincers are fully extended. They prefer to live around cracks and other tight spaces, such as underneath leaves, tree bark, and other animals’ nests. Pseudoscorpions feed on small insects like barklice, ants, mites, and other tiny creatures. They administer venom to their prey, but they are not dangerous to humans.
Comparison of Scorpion Species
When comparing the three scorpion species found in Louisiana, there are several factors to consider.
The Striped Bark Scorpion is characterized by its yellowish to tan color and black stripes on the abdomen. The Southern Devil Scorpion, on the other hand, has an elongated body and is typically reddish-brown in color. Lastly, the Pseudoscorpion resembles a scorpion in appearance but lacks a tail and stinger.
Habitat and Distribution
The Striped Bark Scorpion is commonly found in dry and arid areas, while the Southern Devil Scorpion prefers a more tropical climate. Pseudoscorpions can be found in various habitats, including cracks, tree bark, and animal nests.
Sting and Venom
While the Striped Bark Scorpion and Southern Devil Scorpion both have stingers, their venom is not lethal to humans unless an allergy is present. Pseudoscorpions, on the other hand, are harmless and cannot bite or sting humans.
Considering these factors, it is clear that all three scorpion species have their unique characteristics and adaptations to their respective habitats.
Precautions and Safety Tips
Avoiding Encounters with Scorpions
To avoid encounters with scorpions in Louisiana, it is important to take certain precautions. When camping or spending time outdoors, it is advisable to shake out camping equipment, such as sleeping bags and shoes, to ensure there are no scorpions hiding. Additionally, maintaining a clean and clutter-free home environment can help deter scorpions from entering.
What to Do if You are Stung
If you are stung by a scorpion, it is essential to remain calm and follow these steps:
- Clean the area with soap and water.
- Apply a cold compress or ice pack to reduce swelling.
- Take over-the-counter pain medication, if necessary, for pain relief.
- If symptoms persist or worsen, seek medical attention immediately.
To prevent scorpions from entering your home, it is important to seal any cracks or openings in walls, windows, and doors. Ensuring that windows and doors have tight-fitting screens can also help keep scorpions out. Regularly removing piles of leaves, wood, and other debris from around your home can make your property less appealing to scorpions.
By following these precautions and safety tips, you can minimize the risk of encountering scorpions and reduce the chances of being stung.
