Carolina Wolf Spider
Hogna carolinensis
Lycosidae (Wolf Spiders), Order Araneae. Key family characteristics include excellent eyesight with a distinctive eye arrangement (four small eyes in a lower row, two very large eyes above them, and two medium-sized eyes further back), robust running legs, and the habit of carrying egg sacs attached to the spinnerets and spiderlings on the mother's back.
Physical Description
Robust, hairy body with a distinct cephalothorax and oval-shaped abdomen. The specimen shown is deceased, showing legs curled inward which is a typical post-mortem posture. The cephalothorax features pale radial patterns and a central dark band.
Size Estimate
Large specimen, with a body length estimated around 25 to 35 mm and a leg span reaching up to 70 to 100 mm. This is typical of an adult female Carolina Wolf Spider, which is the largest wolf spider species in North America.
Coloration & Markings
Muted camouflage colors featuring shades of gray, brown, and charcoal. The ventral side of the cephalothorax and parts of the legs display striking black markings, while the dorsal side has longitudinal stripes and mottled grayish-brown tones.
Web Type
Do not build webs to catch prey. Instead, they are active roaming hunters that may construct simple silk-lined burrows or retreat under rocks, logs, and bark.
Eye Arrangement
Typical lycosid pattern: eight eyes arranged in three distinct rows. A bottom row of four small eyes, a middle row with two very large forward-facing eyes, and a top row with two medium-sized eyes set wider apart on the top-sides of the cephalothorax.
Leg Characteristics
Long, thick, and covered with numerous hairs and spines. The legs show distinct gray and brown banding and are held in a powerful stance during life for rapid sprinting across the ground.
Venom & Safety Information
Venom Information
Neurotoxic and cytotoxic venom designed for subduing insect prey. Not potent to humans, though a bite can cause localized pain, redness, and swelling similar to a bee sting.
Medical Significance
Not medically significant. Bites are rare and only occur in self-defense. No systemic effects are expected for healthy humans, though thorough cleaning of the bite area is recommended to prevent secondary bacterial infection.
Safety Recommendations
Avoid handling bare-handed. If found inside, gently capture under a container and release outdoors. Wear gloves when moving rocks or firewood in areas where they live.
Habitat & Behavior
Habitat & Range
Found across North America, particularly in the United States and parts of southern Canada. Prefers open fields, grasslands, deserts, and wooded areas, often hiding under stones, leaf litter, or in self-excavated burrows.
Behavior & Temperament
Nocturnal roaming hunters that rely on speed and exceptional vision to track down prey. Generally non-aggressive toward humans, choosing to flee when disturbed, though they will bite defensively if cornered or handled.
Diet & Prey
Generalist predators that consume a wide variety of ground-dwelling insects, including crickets, beetles, grasshoppers, and occasionally other spiders.
Seasonal Activity
Most active during spring, summer, and early autumn. Adults often seek shelter indoors or in protected outdoor crevices as temperatures drop in late autumn.
Description
The Carolina Wolf Spider is the largest wolf spider in North America, known for its impressive size, excellent camouflage, and formidable hunting prowess. As a ground-dwelling nomad, it commands respect without posing any real danger to humans. Its presence in gardens and yards makes it an exceptional natural pest controller.
Key Features
Large size, robust and hairy build, characteristic gray and brown mottled coloration with a dark-streaked underside, and the distinctive lycosid eye arrangement.
Similar Species
Other large wolf spiders in the genus Tigrosa or Rabidosa. They can be distinguished by specific stripe patterns on the cephalothorax and abdomen as well as regional distribution.
Life Cycle
Females construct a spherical silk egg sac and attach it to their spinnerets, carrying it everywhere. Upon hatching, hundreds of spiderlings climb onto the mother's abdomen and ride there for the first week or two of life. They undergo multiple molts to reach maturity, living up to several years in females.
Ecological Importance
Serves as a top invertebrate predator on the forest or garden floor, playing a vital role in regulating insect populations and providing food for birds, reptiles, and small mammals.
Conservation Status
Not evaluated by the IUCN, but populations are generally stable and widespread across their natural range.
Interesting Facts
Wolf spiders are famous for maternal care, carrying their hundreds of young on their backs. If you shine a flashlight across a lawn at night, the eyes of wolf spiders will reflect the light brightly like tiny green or white headlights.
Photography Tips
Photograph from a low angle at eye-level with the spider. Use a macro lens for eye arrangement and leg details, and ensure good natural lighting or a diffused flash to highlight textures.
