[3] Females carry the egg-sac with them during incubation, so females can be identified in this way during the breeding season. [6], The Carolina wolf spider is venomous, but is not meant as a defense system against threats.
Further, in fact, its venom remains mostly harmless to any large mammal.
Hogna carolinensis spiders have been sighted 32 times by contributing members. Species carolinensis (Carolina Wolf Spider) Synonyms and other taxonomic changes . However, their bite is as painful as the sting of a bee or wasp. From these burrows they then ambush their prey for survival. [6] This adaptation is helpful because it reduces the shifts in food and water needs that in other spiders is associated with large temperature shifts.

Declared in 2000, the species is the official state spider of the state of South Carolina, USA.
[5] There tends to be two main egg carrying seasons, the first in late July and the second in late August. Spiders will flee to try and get far enough from a predator in hopes that they will loses interest in them. Interestingly, the speed of the spider and flee distance are positively correlated, meaning that the spiders that flee farther are able to run away faster, both mechanisms helping their antipredatory reactions.
Carolina Wolf Spider Facts Firstly, for someone with arachnophobia, the sheer size and appearance of the Carolina Wolf Spider can be the source of nightmares.
Follow, If you are a nature enthusiast, if you care about our amazing planet and want to be part of our cause. The bottom row has four small eyes, the middle row has two very large eyes, and the top row has two medium-sized eyes. They are found in burrows located in open fields.
The spider will then keep digging out areas in this manner until they create a burrow that is a sufficient size. Typically, they will make threatening motions like extending their forelegs, spreading their chelicerae, or drumming their palpi at each other. [3] Then, depending on the movement of the female, the male will approach. Occasionally, spiders will take over the burrow of their mother if she has died while her offspring are still spiderlings (10). [12] Lycotoxins change the ion and voltage gradients in their targets, especially targeting the Calcium ion, which is what makes it a paralytic. Hogna Corolinensis, commonly known as the Carolina wolf spider, is found across North America. The tiny eggs are wrapped in a silken sac.
[5] When the eggs hatch, there are about 200 spiderlings per sac. [2] If a Carolina wolf spider is in its burrow when it catches its prey, it will drag it down into the depth, holding onto its victim with its chelicerae (the “jaws” of the spider).[2]. The Carolina Wolf Spider is the largest species of wolf spider in North America. Researchers do not know why this behavior occurs, but they believe the warmth helps the eggs to hatch more quickly. A great way of finding them is with a flashlight held at eye level to reflect light back from their eyes directly toward yours. Based on collected data, the geographic range for Hogna carolinensis includes 1 countries and 13 states in the United States.
They do have large fangs and are venomous, but their venom is not very dangerous to humans and is of no serious medical significance. The large eyes of the spider reflect light brightly and can be spotted more easily at night with the help of a flashlight.
Research suggests that these spiders prefer flatter and more open areas. The Carolina wolf spider is mottled brown with a dark underside. They are the largest of all the wolf spiders found in North America. The orange coloration on the males is a good way to identify a male Carolina wolf spider. This species also does not seem overly aggressive and typically flees from any creature larger than itself. When female Carolina wolf spiders do interact, their behavior can range from merely making foreleg contact to cannibalism. [5] To construct their own burrow, the Carolina wolf spider digs out a small area, spins a web to act as a mat that will hold the structure. It does not wait for prey to get tangled in an intricate web; it seeks out and attacks. [11] As the burrows go deep in the ground, some as deep as 30 cm, they tend to be about 4 °C cooler than the temperature on the surface. Other Characteristic Features: Being poor climbers, they are usually seen at floor-level, hiding under rocks or holes, and making their burrows in the ground (rather than sewing hanging webs). Yet, despite its quite intimidating appearance, this arachnid remains relatively harmless to humans.
The female spider would then carry the young ones for a few weeks until they are large enough to be independent and defend themselves. Size: The females are much larger than the males, with the former’s body length typically being 25 mm (0.98 in), and the latter’s 19 mm (0.75 in), excluding their legs.
All State Insects.
[4], Spiderlings are born near the end of summer and, barring exceptional circumstances like flooding, stay with their mother for the first 6 days of their life. Some are tubes that are just dug straight down while others have bends. Although not too aggressive, Carolina Wolf Spiders are skittish and leery of humans. Hogna carolinensis has also been sighted in the following states: Arizona, Arkansas, Colorado, Florida, Iowa, Kansas, Mississippi, New Mexico, Oklahoma, South Dakota, Texas, Utah, Wyoming. Hogna carolinensis, commonly known as the Carolina wolf spider, is found across North America. Before laying the eggs, the female digs a hole in the ground around 8 inches deep, lining it with spider silk and finally covering with debris from plants. Males die that same summer, but female spiders can live for multiple breeding seasons.
Researchers think the variety in size and shape has to do, in part, with spiders digging the path of least resistance, though there is some correlation between spider and burrow size. As immature spiders, the spiderlings go through multiple instars (growing stages) until they reach breeding age at about three years. Instantly after they crawl out of their silken case, they clamber up the legs of their mother, crowding on the underside of its abdomen. [5] The exact purpose of these turrets is not known, but they are hypothesized to be a lookout or early warning system for potential predators. Carolina wolf spiders tend to live in burrows. Adult females can reach 22–35 mm and adult males 18-20.
Males have orange coloration on their sides. All spiders should be considered dangerous because you don’t want to find out if you’re allergic or particularly sensitive the HARD WAY! [5], During courtship, males will approach the female and make the first move: they will enter into a courtship posture by extending their forelegs. If the female is moving around quickly, the male will too. Because they depend on camouflage for protection, they do not have the flashy appearance of some other kinds of spider and their coloration generally blends with their habitat. Also known as the Giant Carolina Wolf Spider, the Carolina Wolf Spider is the largest wolf spider in North America and is one of the largest of the 2,200+ species of wolf spiders …
[5], It has been noted that when Carolina wolf spiders are brought in to lab conditions for observations, they do not burrow as well as out in the wild. These wolf spiders avoid contact with humans or anything larger than themselves.
Here.
Historically, it was referred known as Lycosa carolinensis, but refinement in taxonomy in the later half of the 20th century led to H. carolinensis, among other many spiders, to be reclassified to how it is known today.
[10], In addition to sight and olfactory senses, Carolina wolf spiders will react to vibrations they sense. Instead it is thought that their venom, which is composed of lycotoxins, is used as a paralytic agent for their prey and as a method of defense against infection from any microbes that may be in their prey.

They live in either self-made burrows or ones they find. Instead, they sit on the edge of their burrow or in some other good ambush location, and attack their prey when it gets near. Because of their nervousness (and speed), they shouldn’t be handled. It is the largest of wolf spiders, typically measuring at 18–20 mm for males and 22–35 mm for females.
[2][7], Carolina wolf spiders are burrowers and therefore do not catch their prey within webs. [2], Though Carolina wolf spiders are not social, research has shown that the offspring that stay with and socialize with their mother after birth have better hunting skills and bigger brains. Based on collected data, the geographic range for Hogna carolinensis includes 1 countries and 13 states in the United States. The Carolina Wolf Spider was named South Carolina’s official state spider in 2000. [5] Though they are diggers, Carolina wolf spiders do not have specialized digging anatomy, so it is sometimes easier to take over the burrow of other small organisms.
Male Carolina wolf spiders flee significantly more than females. [4] The spiders then disperse and find their own burrows or places to live (10). All rights reserved.
Carolina wolf spider burrows vary in size and shape.
They will then extend their palps and vibrate their abdomen, repeating this a few times. This holds true because it forms the largest of the known wolf spiders in its habitat range.
