How to Tell Wolf, Brown Recluse, and Hobo Spiders Apart
A fast brown spider darts across the basement floor. Wolf spider, brown recluse, or hobo?
All three are brown. All three turn up in U.S. homes. All three get blamed for bites that none of them caused. The differences live in body size, markings, eye arrangement, web style, and geographic range.
This guide walks through how to tell the three apart on sight, where each one lives, and which bite warrants a doctor.
Brown recluse fear is a national pastime, but the spider itself is regional. Hobo spider reputation has been walked back by recent research. Wolf spiders look intimidating and rarely matter medically. Confuse the three and you panic over a harmless hunter or dismiss one that deserves attention.
Identification rarely comes from a single feature. It is the combination of body size, the violin marking on a recluse, the chevron stripe down a wolf spider's back, the eye count (6 for the recluse, 8 for the others), the web style or absence of one, and the part of the country you are standing in. Combine 2 or 3 of those signals and identification stops being guesswork. The sections below map the diagnostic markers for each species, the 4 lookalikes worth ruling out, and what current science says about bite risk.
Key Takeaways
- Brown recluses have 6 eyes in 3 pairs and a violin marking behind the eyes. Wolf and hobo spiders have 8 eyes and no violin.
- Wolf spiders build no web and hunt on the ground. Hobo spiders build funnel webs with a narrow retreat at the back. Brown recluses build messy sheet webs in undisturbed corners.
- Brown recluses are concentrated in the south-central and lower midwestern U.S. Hobo spiders live in the Pacific Northwest. Wolf spiders are found across North America.
- Wolf bites are a nuisance. Current research treats hobo bites as low risk. Confirmed brown recluse bites can cause necrotic skin lesions that warrant emergency care.
- If you suspect a brown recluse bite, go to the emergency room. Spider ID at home is unreliable for medical decisions.
Why These Three Get Confused
Wolf spiders, brown recluses, and hobo spiders share a color palette and a body plan. From across the room they all look the same: brown, low, fast. Add recluse fear to the mix and almost every brown spider in a basement gets reported as one. University entomology labs routinely find that the vast majority of submitted recluse samples are something else entirely.
The diagnostic features are eye pattern, markings, body size, web style, and geography. Each signal is more reliable than color. Combining 2 or 3 of them makes identification straightforward without ever handling the spider.
Wolf Spider vs Brown Recluse vs Hobo
Compare body size, markings, eyes, web style, habitat, and range to identify the spider before you decide what to do about it.
Wolf Spider
- Body size: 10 to 35 mm (0.4 to 1.4 in), stocky and hairy
- Color and markings: brown to gray with a darker chevron stripe down the back
- Eye pattern: 8 eyes in 3 rows, with 2 large forward-facing eyes
- Web type: none. Wolf spiders are ground hunters and sometimes dig burrows
- Habitat: garages, basements, ground-floor rooms, foundation lines
- Geographic range: across North America
- Bite severity: nuisance bite. Local pain and swelling resolve in 3 to 5 days
Vacuum it up. Wolf spiders look intimidating but are not medically significant.
Brown Recluse
- Body size: 6 to 12 mm (0.25 to 0.5 in), long thin legs
- Color and markings: uniform tan to dark brown with a darker violin shape behind the eyes
- Eye pattern: 6 eyes in 3 pairs (1 front pair, 2 side pairs)
- Web type: messy, irregular sheet webs in undisturbed corners, closets, storage boxes
- Habitat: attics, basements, stored clothing, cardboard boxes, behind furniture
- Geographic range: south-central and lower midwestern U.S. (parts of TX, OK, AR, MO, KS, TN, KY, MS, AL, GA, IN, IL, OH, IA, NE, LA)
- Bite severity: medically significant. Can cause necrotic skin lesions and systemic symptoms
Outside the verified range, it is almost certainly not a recluse.
Hobo Spider
- Body size: 7 to 14 mm (0.3 to 0.55 in), long legs
- Color and markings: brown with a faint herringbone or chevron pattern on the abdomen, no violin
- Eye pattern: 8 eyes in 2 rows, all roughly the same small size
- Web type: funnel-shaped web with a narrow retreat at the back
- Habitat: ground-level cracks, woodpiles, foundations, basements, garages
- Geographic range: Pacific Northwest, including parts of WA, OR, ID, MT, UT, and into BC
- Bite severity: current research treats hobo bites as low risk and non-necrotic
Look for the funnel web. The web is the easiest hobo confirmation.
8 eyes and no web means wolf spider. 8 eyes plus a funnel web in the Northwest means hobo. 6 eyes with a violin marking in the south-central U.S. means brown recluse. A suspected recluse bite belongs in an emergency room, not at home with a magnifying glass.
Why Eyes and Range Beat Color Every Time
Most people zero in on body color and leg length. Both are worthless for separating these 3 species. All three are brown. All three have long legs relative to the body. The 2 features that actually work are eye arrangement and geographic range.
Brown recluses have 6 eyes, not 8, arranged in 3 small pairs across the front of the head. Almost every other spider in a U.S. home has 8 eyes. A clear photo of the head with 8 visible eyes rules out a recluse on that feature alone. The violin marking is useful as a confirming clue but can be faint or worn, and several harmless spiders carry similar darker shapes. The eye count is more reliable.
Range matters as much as anatomy. Verified brown recluse populations sit in a defined band across the south-central and lower midwestern states. They are not present in any meaningful population in California, the Pacific Northwest, the Northeast, or New England, despite constant claims. Hobo spiders are the inverse. They live in the Pacific Northwest and a few neighboring states. They are absent from the recluse range. In Seattle, the geography alone calls a recluse report into doubt before any other feature.
Wolf spiders confuse people because they are large, hairy, and fast. Size is the giveaway in the other direction. A wolf spider runs up to 35 mm (1.4 in) in body length. A brown recluse rarely tops 12 mm (0.5 in). A hobo sits around 7 to 14 mm (0.3 to 0.55 in). If the spider is larger than a quarter coin, it is almost certainly a wolf spider or another harmless hunter, not a recluse.
Four Brown Spider Lookalikes Worth Ruling Out
Before you commit to a wolf, recluse, or hobo ID, rule out these 4 common brown spiders. Each one regularly gets misreported as a recluse.
-
Cellar Spider (Daddy Long Legs)
Pale tan body 7 to 8 mm (0.3 in) with very thin, long legs. Builds messy webs in basement and garage corners. 8 eyes clustered in 2 groups. Misidentified as a recluse on leg length, but the body is smaller and the legs are far longer in proportion. Harmless.
Spider Identification by the Numbers
Brown recluses have 6 eyes in 3 pairs. Wolf spiders, hobo spiders, and almost every other house spider in North America have 8 eyes. The eye count is the most reliable single visual marker for ruling a recluse in or out from a clear photograph.
Verified brown recluse populations sit in the south-central and lower midwestern U.S. Outside that range, samples submitted as recluses to university entomology labs are almost always misidentified, per research at UC Riverside.
After years of conflicting research, the CDC removed the hobo spider from its list of venomous spiders of concern in 2017. Current entomology research treats hobo bites as low risk and finds little evidence they cause the necrotic lesions once attributed to them.

Two Mistakes That Lead to Wrong Identifications
Calling Every Brown Spider a Brown Recluse
Brown recluse fear is wildly out of proportion to the actual range. Residents in California, the Pacific Northwest, New England, and most of Canada regularly report recluses where no established populations exist. Lab follow-ups on submitted samples almost always find wolf spiders, cellar spiders, common house spiders, or sac spiders instead. Before treating a household sighting as a recluse, check whether your state sits inside the verified range. If it does not, the odds overwhelmingly favor a harmless lookalike. Aggressive home treatment will not change that.
Assuming a Necrotic Wound Confirms a Spider Bite
A skin lesion with a dark center is not, on its own, evidence of a spider bite. Bacterial skin infections (especially MRSA), other insect bites, and several non-bite skin conditions produce wounds that look nearly identical to what people associate with a recluse. Multiple emergency room studies have found that most patients arriving with a self-diagnosed spider bite actually had something else. Treating an MRSA infection like a spider bite delays the antibiotics the patient needs. Let a clinician make the call on a wound, not the internet.
The Bottom Line
Telling these 3 spiders apart comes down to a few reliable signals. Count the eyes if you can: 6 in 3 pairs is a recluse, 8 is something else. Look for the violin marking behind the eyes on a recluse, the chevron stripe down a wolf spider's back, or a funnel web in a corner for a hobo. Then check your geography. Recluses live in a specific band of states. Hobos live in the Pacific Northwest. Wolf spiders are everywhere.
Home ID is useful for deciding whether you have a nuisance pest or one that warrants caution around children and pets. It is not a substitute for medical care if a wound is changing, spreading, or causing systemic symptoms. When in doubt about a bite, go to the doctor. When in doubt about an infestation in a basement, attic, or storage area, a professional inspection confirms the species, identifies the conditions feeding the population, and puts a targeted treatment plan in place.
Confirm the species before you treat.
A professional inspection identifies the actual spider, the harborage points feeding the population, and the targeted treatment plan that resolves it. You stop guessing and stop spraying for the wrong species.
Spider Identification FAQs
Common questions about telling wolf spiders, brown recluses, and hobo spiders apart.
-
How do I quickly tell a brown recluse from a wolf spider? Toggle answer for: How do I quickly tell a brown recluse from a wolf spider?
Look at the eyes and the size. Brown recluses have six eyes arranged in three small pairs and are rarely larger than three eighths of an inch in body length. Wolf spiders have eight eyes (with two large prominent ones facing forward) and can be over an inch long, stocky, and visibly hairy.
If the spider is bigger than a quarter, it is almost certainly not a recluse. If you can count eight eyes in a clear photo, you have ruled out a recluse on that single feature.
-
Do brown recluses live in California or the Pacific Northwest? Toggle answer for: Do brown recluses live in California or the Pacific Northwest?
No. Verified brown recluse populations are concentrated in the south-central and lower midwestern United States: parts of Texas, Oklahoma, Arkansas, Missouri, Kansas, Tennessee, Kentucky, Mississippi, Alabama, Georgia, Indiana, Illinois, Ohio, Iowa, Nebraska, and Louisiana.
California, the Pacific Northwest, New England, and most of Canada have no established recluse populations. UC Riverside research consistently finds that spiders submitted as recluses from those regions are almost always wolf spiders, cellar spiders, or common house spiders instead.
-
Are hobo spider bites really dangerous? Toggle answer for: Are hobo spider bites really dangerous?
Current research considers hobo spider bites low risk and finds little evidence they cause necrotic lesions. The CDC removed hobo spiders from its list of venomous spiders of concern in 2017 after years of conflicting research.
A hobo bite can cause local pain or redness like many spider bites, but the necrotic reputation it carried for decades is no longer supported by the evidence. Wolf and hobo bites are nuisance level for nearly everyone.
-
What does the violin marking on a brown recluse actually look like? Toggle answer for: What does the violin marking on a brown recluse actually look like?
It sits on the cephalothorax (the section behind the eyes, in front of the abdomen) and looks like a darker violin or fiddle shape with the neck of the violin pointing toward the rear. The body around it is uniform tan to dark brown.
The violin can be faint, worn, or partially obscured, and several harmless spiders have darker thoracic markings that resemble it. Use the violin as a confirming clue, not the only one. The six-eye arrangement is more reliable when both are visible.
-
I think I was bitten by a brown recluse. Should I just watch the wound? Toggle answer for: I think I was bitten by a brown recluse. Should I just watch the wound?
If you suspect a recluse bite, especially with expanding redness, a darkening center, severe pain, fever, or chills, go to the emergency room. Do not try to diagnose it at home or wait it out.
Most suspected recluse bites turn out to be something else: bacterial skin infections (especially MRSA), other arthropod bites, or non-bite skin conditions that look almost identical. Treating an MRSA infection like a spider bite delays the antibiotics the patient actually needs, and only a clinician can sort that out safely.
-
Why do I keep finding wolf spiders in my basement? Toggle answer for: Why do I keep finding wolf spiders in my basement?
Wolf spiders are ground hunters that follow other insects. Basements, garages, and ground-floor utility rooms attract them because crickets, beetles, and other prey congregate near foundations and damp areas.
Cut down the prey base and the wolf spiders thin out. Reduce indoor moisture, seal foundation cracks, fix any door sweeps that have lost contact with the threshold, and clear leaf debris from along the exterior wall. Wolf spiders will move on once the easy meals are gone.
-
I found a funnel web in my yard. Is that a hobo spider? Toggle answer for: I found a funnel web in my yard. Is that a hobo spider?
Funnel webs across lawns, shrubs, and ground cover are most often grass spiders, not hobos. Grass spiders build the same funnel structure but with prominent stripes down the back and very long spinnerets visible at the rear of the abdomen. Hobo spiders nest in cracks at ground level: woodpiles, foundations, basement corners, garage cracks.
Geography also matters. Hobo spiders live in the Pacific Northwest. If you live east of the Rockies and find a funnel web outdoors, it is almost certainly a grass spider, which is harmless.
