I found this little friend behind my couch while looking for something. She appears to be a southern house spider.
What are they like — temperament, environment, bite, etc?
I have her in a jar. I might find a more semi-permanent solution for her later (a container I used to house a baby terrestrial tarantula who outgrew it). I don’t want her to go back to her home behind my couch (I found her webs as well as evidence of past feasts she made of escaped tarantula food — I think we’ve been “roomies” for some time, and I’ve found young males inside before as well) because I don’t want her to get squished or for her to end up in a situation where she might feel the need to bite — or to get eaten by my dog. However I don’t want to throw her outside because it’s very cold right now (I realize she is a native wild animal, but I don’t know what her species does to combat the cold, if anything special — I don’t want to just throw her out into the cold unprepared). I was thinking I could feed her for a few months and release her in an abandoned barn on a local plantation this spring.
Can you give me any general information on these guys, and confirm that she is what I think she is? Thanks!

Female Southern House Spider

Female Southern House Spider

Hi Denise,
We concur with your identification of this female Southern House Spider which looks exactly like this individual posted to BugGuide.  There is not much information on the Southern House Spider on the BugGuide info page, except for this comment: “Females are frequently mistaken for small tarantulas or trapdoor spiders. Males are often mistaken for recluse spiders (Loxosceles). This is a totally harmless species that builds “messy” webs emanating from crevices, often on the outside of homes.”  So, she is totally harmless, but that does discount that a large individual might bite if carelessly handled.  We will turn elsewhere to seek additional information.  According to Featured Creatures:  “Females may live up to eight years” which means you might want to entertain the idea of keeping her as a pet as long as you have tarantula rearing experience.  While Spiders.us does not have any information on the bite, there is a photo of a large female being held.  Some of the best firsthand information we found is on a BugGuide posting by Mamata Polle who writes:  “These make suprisingly good house guests if you can tolerate their highly effective, (Though not very pretty,) web making style. Females tend to stay put until either they grow out of their retreat, they are starving to death, or their web is destroyed. For the past 13 years I’ve been living with this type of spider and have never been bitten by one, they are docile and very good at snaring flies, roaches and other household invaders. Usually when I see their webs I just leave them be, but one of our cats has recently decided he likes to eat spider webs… (Weird huh,) and that is how I ended up with Kholi, (Pictured above.) She was wandering around looking to rebuild her web where it had been, (And said cat would have come back to eat it again!) so I decided to capture and provide a home for her. She produces webbing as needed and without hesitation, which is good because she won’t eat without it! Southern House Spiders totally depend on their webs to catch food; their eyesight is poor, so they seem to, “Feel” their prey when it gets stuck and squirms, then they pounce. It is VERY dificult to get them to eat from a pair of tweezers, one must be very… patient. However they will take water very easily when they’re dehydrated, even off your finger. The first time I had one do this I thought it was biting me, but it wasn’t, it was just sucking the water out of my damp hands, which didn’t hurt. One of the best ways to distiguish this species other than their general appearence is the very fine silver hair they possess, which is most visible at the joints.  BTW: They will sometimes very convincingly play dead when threatened…:P And if they don’t mate, they can live an incredibly long time. (I have been watching one adult female for three years!)  Be Well, God Bless and Thanks for Reading. :)”
Regardless if decide to keep her as a pet or to release her back into a plantation barn in the spring, because of your sensitivity regarding the welfare of this female Southern House Spider, we are tagging your posting with the Bug Humanitarian Award.

I found this little guy amongst 100s of others the same size and bigger at my work. They are under an overhang shelter to an old bombshell bunker that i had to hose the nest and webs off from hanging. Theres plenty of lights that constantly stay on under there. And these critters are couped up in small round tunnel webs and balls of a messy webbing. Im wondering what they are and if they are poisonous. They are pretty big up to 2 1/2 inches including the leg length.

Female Crevice Weaver Spider

Hi Keith64,
This is a female Crevice Weaver Spider,
Kukulcania hibernalis, and you can compare your photo to this image on BugGuide.  According to BugGuide:  “Females are frequently mistaken for small tarantulas or trapdoor spiders. Males are often mistaken for recluse spiders (Loxosceles). This is a totally harmless species that builds ‘messy’ webs emanating from crevices, often on the outside of homes.”  Eric Eaton has an excellent blog posting on Crevice Weaver Spiders on Bug Eric.

Crevice Weaver Spider

Dear Eric,
Despite its frightening appearance, you don’t need to be concerned.  This is a female Crevice Weaver Spider,
Kukulcania hibernalis, which we identified on BugGuide.  According to BugGuide:  “Females are frequently mistaken for small tarantulas or trapdoor spiders. Males are often mistaken for recluse spiders (Loxosceles). This is a totally harmless species that builds “messy” webs emanating from crevices, often on the outside of homes.”

Dark Fishing Spiders- Very helpful in the house
June 14, 2011 4:25 am
You might be interested to know that dark fishing spiders absolutely love to hunt and eat brown recluses. I got rid of an infestation using my girl. (girl because she has probably more than 100 babies that I released.) If people knew about her kind eating the dangerous spiders, maybe fewer would be killed! She may be big and intimidating, but she sure helped with that problem before I got bit by a recluse a second time!
My wolf spider hunted them a bit too, but went after crickets more. Now those are spiders to have around the house! Especially because most pesticides don’t effect recluses!
Another thing about spiders-
Recluses like moisture and can climb through pipes. I had several come out of an unused sink drain and one came up through the toilet! Watch out so you don’t get your butt bit.

Cassie’s Fishing Spider

Dear Cassie,
Thanks so much for your email.  We hope the advice you offer will prevent the Unnecessary Carnage of large and scary, though harmless Fishing Spiders.  We are illustrating your email posting with photos from our archives of a Fishing Spider and a Brown Recluse.

Cassie just provided us with another account of raising Fishing Spiders and them feeding on Brown Recluse Spiders.  We were able to replace the Fishing Spider image from our archives with one of Cassie’s own photos.

recluse or wolf spiders?
Location: Las Vegas nevada
November 21, 2010 10:05 am
I seen many spiders around my home when since my family and I moved in two years ago. My husband thought they were wolf spiders and told me not to worry so I wasn’t to concerned about them.
Recently I’ve seen pictures of both the recluse and wolf spiders and now I’m confused as to what mine are.
I’m concerned for the safety of my kids since there are such a large number of them.
I try to grab my camera every time I see an interesting or scary bug. I’ve got pictures of different spiders, they might not even be the same species.
Any help would be greatly appreciated.

Male Crevice Weaver Spider, not Recluse Spider?

Dear Emm,
Only one of the spider images you attached is a Recluse Spider, and since the quality of that image is different, we are surmising that perhaps you didn’t even take that photo, though your email does not indicate that.  We will attempt to identify your other spiders.

Female Crevice Weaver Spider, we believe

Update/Correction
Hi again Emm,
Now we are having second thoughts.  We believe all of your spiders Crevice Weaver spiders in the genus
Kukulcania, possibly the Southern House Spider, Kukulcania hibernalis.  The lighter colored one with the longer legs looks just like a male Southern House Spider posted to BugGuide.  The other specimens look like females that are posted to BugGuide.  We would encourage anyone reading to confirm or correct this identification.

Female Crevice Weaver Spider, we believe

Eric Eaton Concurs
Hi, Daniel:
… Well, it is definitely a species of Kukulcania, but I don’t think that species (K. hibernalis) ranges into Nevada.  Likely a different species.
Eric

Update from Emm
I took all the photo’s myself. The first photo was of a spider that was inside my home. I took that picture after putting the spider inside a plastic container, that’s why the quality looks different. the other spiders were all outside and  I took the photo’s from a distance.
I wasn’t aware that I could identify the spiders by their eye configurations. next time I’ll know where to point the camera. I read that recluse spiders don’t have fine hairs on their legs and it’s easy to see that there is hair on the legs of my spider which leaves me to believe that you correctly identified mine to be house spiders.
I know now not to do an image search to help me identify insects. the results were very misinforming
I appreciate all your help.  If you’re interested I have photo’s of other insects, most of the pictures are in good quality. the photo’s are of aphids, a June beetle, an adult and a juvenile praying mantis, a male carpenter bee and a beetle. I’m unaware of the exact species but it’s bigger than my hand. I took pictures of it from where it was when I first seen it and then took more pictures of it while it was in a container. .  if you’d like to see them let me know. I’m not a photographer but I think some of them are good shots
Thank You for all your help; Emm
p.s.  All of the bugs that I’ve captured were taken away from my house and set free. I don’t kill them.

Brown Recluse?
March 29, 2010
We found this spider in Cleveland, Texas this past February while cleaning out a neglected bookshelf. It was between the books in a rather disorderly looking web. The house it was found in is in a wooded area. We’ve been keeping it in a container with wound wire for observation since, and it has established an intricate, cob-webby web between the wires and is living on a steady diet of mosquito hawks and silverfish. We’ve done a lot of image searching for an identity, but the closest we can find is that it’s a brown recluse. However, it lacks a distinct violin marking (although a dark line similar to the violin neck runs down the cephalothorax), the pedipalps are much more defined and less tufty, and the legs seem to be less spindly. We haven’t been able to get a coun t on the eyes, as they’re a bit hard to see. We’ve noticed some small indentions in pairs on the dorsal side of the abdomen, no idea what those are. If its behavior is of any help, we’ve noticed that it cuts its finished prey from its web to let it fall (although perhaps that’s common in spiders). Any help would be much appreciated! Also, if you happen to know, we’d love to know what those indentions are (pictured in photo 3)! Thanks very much.

Crevice Weaver Spider

Dear Laura and Michael,
You may rest assured that this is not a Brown Recluse.  It is a Crevice Weaver Spider in the genus Kukulcania, and it is well represented on BugGuide.  According to BugGuide:  “These spiders create a tube-like retreat in cracks.   This spider varies greatly in color from light brown to dark black. Females are generally grey to black while the males are tan. Males look very similar to the Recluse spiders, except they have much longer pedipalps, eight eyes (not six as in the Recluse family), and very long front legs.
“  It is our opinion that your specimen is a female.
