Scorpions in Tennessee: A Closer Look

Tennessee may not seem like prime scorpion territory, but these fascinating creatures do in fact call the Volunteer State home. While scorpions in Tennessee are relatively small and their stings rarely cause serious harm, many residents and visitors still want to know more about these misunderstood arachnids.

This in-depth article will provide a closer look at Tennessee’s scorpion species, their habits, where they live, and how to avoid encounters.

Overview of Tennessee’s Scorpion Species

There are two main species of scorpions found in Tennessee:

Southern Devil Scorpion

The Southern Devil Scorpion (Vaejovis carolinianus) is native to Tennessee. It has a dark reddish-brown body and tan legs. The pincers are thick and the tail is wide with a sizable stinger.

This nocturnal species likes humid climates and is often found in leaf litter or under rocks and wood. It may wander indoors on occasion Its sting causes mild pain, swelling, and redness but is not considered dangerous.

Striped Bark Scorpion

The Striped Bark Scorpion (Centruroides vittatus) is an introduced species in Tennessee. It has yellowish to tan coloring with two prominent dark stripes on the abdomen.

This scorpion inhabits a variety of ecosystems across the state and hides under rocks, vegetation, and man-made structures. It has a slender, long tail and stinger capable of inflicting a painful (but rarely deadly) sting.

Habits and Behaviors

Tennessee’s scorpions are solitary, nocturnal predators. They emerge at night to hunt insects, spiders, and other small prey. During the day, they hide in burrows, under rocks and wood, and in other natural nooks and crannies.

Scorpions glow bright blue-green under ultraviolet light, so blacklights are often used by researchers and enthusiasts to locate them. All scorpions fluoresce under UV light due to the presence of beta-carboline in their exoskeletons.

In terms of reproduction, scorpions employ a courting ritual called the promenade à deux. Following an intricate dance, the male deposits his sperm in a spermatophore and guides the female over it. She stores the sperm and uses it to fertilize her eggs. The young scorpions ride on their mother’s back until their first molt.

Where to Find Scorpions in Tennessee

Most of Tennessee’s scorpions reside in the eastern part of the state within the Smoky Mountains region. Scorpion populations are concentrated in counties such as Sevier, Blount, Monroe, and Polk.

Prime scorpion habitat includes forests, wooded areas, and environs with plenty of rocks, leaf litter, and fallen logs to hide under. Lawns, gardens, and man-made structures also provide suitable shelter.

The best times to observe scorpions are at night and while moving natural debris. Shake out boots and gear if spending lots of time in the outdoors. Also be vigilant in crawlspaces, basements, bathrooms and other humid areas inside homes where scorpions may wander.

Stings and Preventative Measures

The good news is Tennessee’s scorpions pack a relatively mild, non-lethal venom comparable to a bee or wasp sting. There is potential for a more severe reaction in those allergic. Seek medical attention for persistent or worsening symptoms.

To avoid encounters, seal any cracks around the home, keep firewood and debris piles away from the foundation, eliminate standing water, and check boots/gear before use.

Captured scorpions can be safely relocated by gently sweeping or brushing them into a dustpan or other container. Wear thick gloves when handling them.

Fascinating Creatures

While many dislike and fear them, scorpions are captivating creatures that play an important ecological role. Their venom helps them subdue prey and defend against predators. Other adaptations like sensitive hairs and pincers also aid their survival.

Despite their reputation, Tennessee’s scorpions do not seek out or intentionally harm humans. With proper awareness and caution, encounters can be avoided. Their unique attributes and stealthy hunting under the cover of darkness make scorpions compelling denizens of Tennessee’s forests and mountains.
