Carolina Wolf Spider
Hogna carolinensis
Lycosidae (Wolf Spiders), Order Araneae. Key family characteristics include excellent eyesight featuring a distinctive arrangement of eight eyes in three rows, robust running legs, and the habit of carrying egg sacs attached to the spinnerets and young spiderlings on the mother's back.
Physical Description
Robust and solidly built with a stout, oval abdomen and a distinct, longer cephalothorax. The body is covered in fine, velvety hairs giving it a matte texture. Females tend to be noticeably larger and bulkier than males.
Size Estimate
Body length ranges from 22 mm to 35 mm (nearly 1.5 inches), with a leg span reaching up to 7 to 10 cm. This specimen appears to be a mature or sub-adult wolf spider based on its robust proportions.
Coloration & Markings
Predominantly earthy tones of grey, brown, and tan. The cephalothorax features dark lateral bands, and the underside of the sternum and parts of the venter are often pitch black, which is a key diagnostic feature for this species.
Web Type
Does not build a web to catch prey. Instead, they are active roaming hunters that may construct simple silken retreat burrows under stones, logs, or in the ground.
Eye Arrangement
Eight eyes arranged in three rows (4-2-2). The bottom row consists of four small eyes, the middle row has two very large forward-facing eyes, and the top row has two medium-sized eyes set further back on the head.
Leg Characteristics
Legs are stout, moderately long, covered in fine hairs and spines, and often faintly banded. They radiate outward in a typical lateral-facing hunting posture and are adapted for rapid bursts of speed.
Venom & Safety Information
Venom Information
Contains neurotoxic and cytotoxic components used to immobilize insect prey. The venom has very low potency relative to humans and is not medically significant.
Medical Significance
Harmless to humans. A bite may cause localized pain, redness, and mild swelling similar to a bee sting, but it carries no systemic danger. Medical attention is rarely needed unless an allergic reaction occurs.
Safety Recommendations
Avoid handling bare-handed to prevent accidental defensive bites. If found indoors, gently guide the spider into a container using a piece of cardstock and release it outdoors.
Habitat & Behavior
Habitat & Range
Found throughout North America, particularly common in the United States and parts of Canada. Prefers open fields, grasslands, deserts, gardens, and sometimes wanders into ground-level areas of homes.
Behavior & Temperament
Active nocturnal hunter that relies on stealth and incredible speed rather than webs. They are generally timid and prefer to flee when disturbed, though females guarding egg sacs may display defensive postures.
Diet & Prey
Generalist carnivore feeding primarily on ground-dwelling insects, crickets, beetles, grasshoppers, and occasionally other spiders.
Seasonal Activity
Most active during the warm spring, summer, and autumn months. Mating typically occurs in late summer, and adults overwinter in burrows or protected crevices.
Description
The Carolina Wolf Spider is North America's largest wolf spider, known for its impressive size, earthy camouflage, and nomadic hunting lifestyle. Rather than spinning webs, it prowls the ground at night in search of prey. Despite its formidable appearance, it is a shy creature that provides valuable pest control services around yards and homes.
Key Features
Large size, earthy brown and grey coloration with dark markings, pitch-black coloration on the underside of the sternum, and the characteristic wolf spider eye arrangement with two large prominent anterior-median eyes.
Similar Species
Tigrosa grandis and other large wolf spiders. Distinguishing the Carolina Wolf Spider often relies on examining the distinct pitch-black coloration on the ventral sternum.
Life Cycle
Females construct silken egg sacs and carry them attached to their spinnerets. Upon hatching, hundreds of spiderlings climb onto the mother's back and ride there until their first molt. They undergo multiple molts over a 1 to 2-year lifespan.
Ecological Importance
Acts as an apex predator among terrestrial invertebrates, playing a crucial role in regulating insect populations and serving as a food source for birds, small mammals, and reptiles.
Conservation Status
Not evaluated by the IUCN, but populations are widespread, stable, and resilient to human development.
Interesting Facts
The Carolina Wolf Spider is the official state spider of South Carolina. When illuminated with a flashlight at night, their eyes reflect a bright green glow due to a specialized light-reflecting layer called the tapetum lucidum.
Photography Tips
Photograph from a low angle to capture the spider's face and eye arrangement. Use natural lighting or a diffused flash, maintain a respectful distance to avoid startling it, and try to capture the underside if possible for ID.
