Arizona Brown Spider

Arizona brown spiders are likely what you came across if you’ve ever been moving rocks or reaching up in the attic and happened to come across a little brown spider.

These spiders are members of the family of recluse spiders called Loxosceles. The well-known brown recluse spider, a poisonous species often found throughout the Midwest area, is another member of the recluse family.

You should be aware of the following information on the Arizona brown spider.

Arizona Brown Spider Identification

Due to their violin-shaped cephalothorax, recluse spiders are sometimes known as “fiddleback” or “violin” spiders.

However, the hue of the desert recluse is almost always a consistent shade of brown, making it hard to notice the violin marking. Recluse spiders are sometimes mistaken for striped wolf spiders and other spiders with dark patterns.

Recluse spiders can reach a diameter of up to 1″ at full maturity, including their leg spread. The fact that recluse spiders have six rather than eight pairs of eyes is one way in which they differ from other spiders.

Recluse webs are asymmetrical, sticky, and mainly flat. They are not frequently observed by humans and are simple to miss.

Asking a specialist is the best method to determine if the spider is a recluse. To assist you in identifying them, we would be pleased to examine a specimen you have captured or photographs you have taken.

Arizona Brown Spider Habitat

The warm climates of the southwestern United States, Mexico, and some regions of Central America are preferred by Arizona brown spiders. These spiders live in the naturally existing rock fissures or trash heaps in the deserts where they are endemic.

Arizona brown spiders, however, have discovered that human homes and yards provide for a better environment, and they are frequently drawn to attics, crawl spaces, rock landscaping, and trash heaps.

Once an Arizona brown spider locates a good location, they often remain and multiply frequently. This may result in extremely high spider populations in some areas.

13 Brown Spiders Found in Arizona

There are 13 typical spiders that you could see in Arizona. Most spiders are absolutely safe to people and pose no threat, however occasional bites may cause minor discomfort and swelling.

There are some that you should be careful of, although they typically will flee from you rather than attack a person.

There are 13 common spiders in Arizona, including the following:

Desert Blonde Tarantula

Common names include Mexican blond tarantula, Arizona blond tarantula, and desert blonde tarantula.

The desert blonde tarantula could seem menacing. It is a large burrowing spider with a leg span of up to five inches (13 cm), and it is often seen during the wet summer months.

Males have a red belly, a copper head space, and black legs whereas females often have a tan color.

Females have huge burrows that measure two inches (5.1 cm) in diameter and can grow to a body length of 5.6 cm.

These spiders are widespread in Arizona and New Mexico, where they reside in desert soil and dig deep tunnels to protect themselves from the arid climate.

Western Desert Tarantula

A brown, large-bodied, burrowing spider known as the western desert tarantula is frequently spotted in southwestern deserts during the summer or wet season. Throughout the United States, it is known that these spiders are common in Arizona and New Mexico.

The body length of an adult member of this species ranges from 3 to 5 inches (8 to 13 cm), with females being bigger than males. The male western desert tarantula has a reddish-brown abdomen and black legs, whereas the female is often uniformly tan or light brown in appearance.

This spider frequently inhabits desert soils and can withstand extreme weather, as suggested by its name. In order to locate prey while hiding within a tunnel, it may also dig burrows and cover the entrance with silk strands.

The western desert tarantula is one of the less hazardous tarantulas in the Theraphosidae family and its venom is not harmful to humans.

Brown Recluse

The Brown Recluse is the final human-venomous spider found in Arizona. They enjoy hiding in dim areas like closets, sheds, garages, and woodpiles. The design on their back that resembles a violin makes them easy to identify. The severity of a Brown Recluse bite might vary, but if it goes untreated, symptoms can worsen fast.

Giant Crab Spider

One of the largest spiders you will come across in North America is the giant crab spider, sometimes referred to as the golden huntsman spider. Except for their legs, their entire body can fit within the palm of an adult hand.

A stripe that runs down the middle of the rounded abdomen and ends in a point is present. Short hairs cover the legs and head area (cephalothorax), which are both sandy brown in color. The tips of the foot are a deeper color.

Common House Spider

The common house spider, a smaller brown spider that dwells in and around habitations, is another brown spider found in Arizona. The color of common house spiders ranges from brown to almost black, and their bodies frequently have patterns in various tones.

The papery brown egg sacs left behind in house spiders’ webs make them simple to recognize. Males typically measure between 0.15 and 0.19 inches in length, while females can grow to a length of 0.20 to 0.24 inches.

Additionally, females have an abdomen that is more rounded and bulbous than males. Despite the fact that these brown spiders frequently coexist with people, their size and coloring enable them to readily avoid detection.

Due to their similar appearances, house spiders are sometimes mistaken for the far more hazardous brown recluse spider. House spiders, on the other hand, are not thought to be harmful to people.

They are rarely hostile and only sometimes bite people out of self-defense while being grabbed or squeezed. In contrast to the brown recluse, whose bites can linger for days or weeks, their bites recover fast.

Carolina Wolf Spider

The biggest wolf spider species in North America is the Carolina Wolf Spider. These bashful spiders don’t construct webs and prefer to hide in holes. When provoked, they may bite people. Humans may experience swelling and irritation after being bitten, although this is typically not hazardous.

Western Spotted Orbweaver

Members of the orb-weaver family, notable for its elliptical webs, include Western Spotted Orbweavers.

The spider lies in the middle of its web, upside down, waiting for prey to become entangled. They prefer places with little vegetation.

They have an abdomen that is bulb-shaped, brown with yellow patches on the sides, and a brown line that passes through yellow triangles in the middle. The abdomen is covered with a line of yellow spots.

When the females lay their eggs in the fall, you may usually find them in open fields, gardens, parks, and empty logs.

Huntsman Spider

Because of their enormous size and distinctive crab-like appearance, huntsman spiders (family Sparassidae) are sometimes known as gigantic crab spiders.

Large huntsman spider species are sometimes mistaken for tarantulas. However, their legs, which are twisted so that they protrude forward in a crab-like manner rather than being joined vertically to the body, are what most distinguish them.

While the rest of their bodies are uniformly smooth-haired or fuzzy, their legs feature relatively pronounced spines. Huntsman spider species come in a variety of brown colors. A huntsman spider’s body is typically 0.7 inches (1.8 cm) long, but its leg spread alone can measure up to 5 inches (15 cm).

Huntsman spiders typically reside beneath rocks and in cracks in tree bark since they are endemic to tropical and warm temperate environments. However, they occasionally stray into private residences, so you’re more likely to see them in sheds, garages, and other less congested locations.

These brown spiders forage and hunt insects and other invertebrates rather of making webs. Huntsman spiders are known to bite people as a kind of self-defense, especially when females are actively guarding their egg sacs and young against alleged dangers. However, bites only result in minor symptoms and typically don’t need medical care.

Giant Daddy Long Legs

Although they may grow up to 7 inches long, the Giant Daddy Long Legs are not to be frightened. They are distinguished by having long, wiry legs. They are concealed behind rocks and logs. They will occasionally conceal themselves in your house’s basement or garage, which are both peaceful regions.

They are opportunistic feeders who will consume everything. They will consume other spiders, insects, decaying plants and animals, as well as discarded human food.

Arizona Black Hole Spider

The Filistatidae family includes the states of Nevada, California, and New Mexico in addition to Arizona, where the Arizona black hole spider is native.

This black spider has a velvet-like appearance. In cracks in buildings, they frequently spin their webs.

The body length of a female can reach 13mm, making her bigger than a male. The male has shorter legs, a slimmer torso, and is smaller.

Grass Spider

Arizona is home to harmless brown grass spiders. Their two noticeable hind spinnerets and the arrangement of their eight eyes into three rows make them immediately recognisable. Two eyes are in the top row, four are in the middle row, and two are in the bottom row with spaces between them that are wider than those in the top row.

Grass spiders have lighter stripes on their legs and two dark brown bands going down either side of their cephalothorax. Larger creatures can reach a body length of around 19 mm.

In general, spiders are known for using their webs to capture prey, however grass spiders do not do this. They are incapable of adhesion and weave sheet webs with a funnel shelter on one side. Because of this, the grass spider’s web is not sticky, but these spiders compensate by moving extremely quickly in search of prey.

Marbled Cellar Spider

A typical home spider is the marbled cellar spider. In dark, quiet regions of homes, such as basements and attics, they frequently construct webs and build their nests. These spiders commonly share a single web in small groups. Despite being considerably smaller than their Daddy Long Leg counterparts, they have long legs like them.

Their name refers to the marbling-like pattern on their tan or white legs, which have black bands around the joints.

Varacosa Gosiuta

Another wolf spider from the Lycosidae family that you can come across in Arizona is this one.

This spider, one of six wolf spiders found in North America, was originally reported in 1942.

Arizona Brown Spider Potential Issues

In Arizona, most spiders are not harmful to people. The Arizona brown spider, on the other hand, possesses a poisonous bite that can result in symptoms ranging from minor skin irritation to fatal responses.

The most typical symptoms at the bite site are redness and an expanding sore. Additionally, tissue necrosis, or tissue death, can be brought on by the venom.

Necrotic tissue has the potential to progress into a major infection that, if not immediately and well treated, might be deadly. Seek immediate medical attention if you believe you may have been bitten by an Arizona brown spider.

Arizona brown spider bites may be very painful, so it’s usually preferable to prevent these pests out of your house in the first place.

Prevention

It’s crucial to maintain your home clean and organized in such places since recluse spiders like to hide in storage spaces, woodpiles, and mounds of trash and clothing. On firewood or other objects you might bring home from the desert, recluse spiders might hitchhike into your house.

Keep wood waste placed far from your home to avoid recluse spider infestations. Don’t store firewood indoors; keep it stored outdoors. Don’t leave garments piled up on the floor; pick it up instead. Wearable goods, such as boots or gloves, should be stored in airtight containers or sealed plastic bags.

Recluse Spider Bites

An initial red, swollen region that might turn into a blister is the result of a recluse bite. Recluse bites can become open, weeping sores if left untreated. Consult a doctor right away if you suspect you’ve been bitten by a recluse spider because everyone’s response to their bites is different.

Although they can be unpleasant, recluse spider bites are seldom lethal. Recluse spider bites are frequently misdiagnosed as other illnesses and skin disorders.

You could be responding to anything else unless you get the telltale puncture marks on your skin or can see the spider actually biting you. Consult a doctor if you have any questions.

Always use gloves while handling yard trash and wood debris, clearing up seldom-used storage spaces, or attics to avoid getting bitten by recluse spiders. Before putting on clothing that you have picked up off the floor, shake it. Always double-check your footwear and stored apparel before putting them on.

Conclusion

Many desert animals can sting or bite you. The majority of the spiders in Arizona are not poisonous, which is excellent news. If you are bitten by a spider other than the Black Widow, Brown Recluse, or Arizona Brown Spider, the worst that can happen is a small bit of discomfort and edema.

When you’re out exploring in Arizona, it’s a good idea to keep an eye out for those three deadly spiders since their bites may be dangerous.
