Greetings,
I was sitting on my sofa and I saw this spider walk across my living room. It looks to me that it could be a brown recluse. Or maybe a trap door spider?
Any help would be greatly appreciated!

Male Southern House Spider

Dear John,
This does appear to be a Brown Recluse Spider, and the large pedipalps indicate this is a male, similar to the one pictured in this BugGuide posting.

Correction:  Male Southern House Spider
Thanks to Catherine Scott and Sean McCann for writing in with comments correcting our identification of this male Southern House Spider.

Alas, we did not have a camera handy when we made this exciting sighting of a reddish colored, male Southern House Spider which is reported from Los Angeles according to BugGuide.  We had to take a close look to ensure this was not a Recluse Spider.

I was out I was out getting silverfish for my blue belly lizards. And underneath one of the two by fours on the deck was this pretty large spider. which I have never seen in my 50 years living here. I like spiders because they eat mosquitoes and other nasy pests. so can you help me identify it?

Dear Fixitwill,
Though your image lack critical clarity, we believe this might be a female Crevice Weaver Spider in the genus
Kuculcania.  See BugGuide for some images.

Wow thank you so much for your time!! It was hard to get a good picture because it kept moving around on me.

Dear J. Bressler,
We believe this is a Crevice Weaver Spider in the genus
Kukulcania, and a member of the genus found further east is known as the Southern House Spider.  You can compare your image to this BugGuide image and to Southern House Spiders on Spiderz Rule.

I found this big guy in my yard, polled my friends, half say it’s a brown recluse, half say it’s harmless… One guy said “it’s just a penny”…
I live in the high desert in Southern California, it’s super dry and hot. Help me out here!

Male Crevice Weaver Spider, we believe

Male Crevice Weaver Spider, we believe

Hi Roni,
We are going to side with the half that say it is harmless.  Brown Recluse Spiders have a violin pattern on the cephalothorax .  Male Crevice Weaver Spiders in the genus
Kukulcania, including the male Southern House Spider, Kukulcania hibernalis, are frequently mistaken for Brown Recluse Spiders.  BugGuide only lists the Southern House Spider as far west as Texas, but a relative, Kukulcania geophila, is found in California and this image from BugGuide looks very similar to your individual.  Of the entire genus Kukulcania, BugGuide notes:  “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.”  Finally, according to BugGuide, the Brown Recluse Spider does not get as far west as California.

Some time ago, I think last winter (maybe the one before), I wrote to you about a southern house spider I caught behind my couch and was going to release in the spring — you suggested I keep her, as I have tarantula experience, and I did. She’s fat and happy to this day, and she’s grown some.
This winter, I have another friend. She lives above my bed, behind an animal-skin wall hanging. I saw the web and meant to brush it away, off of my stuff (it makes all of the fur stick together and look bad), but then I saw her and realized the space was occupied. For now, and very probably permanently, she can stay, as it’s somewhere she’s safe from us accidentally hurting her, and from us being bitten on accident. I’m probably going to start feeding her periodically, so she will be more likely to stay put, instead of setting up camp somewhere less safe. I noticed her weeks ago, but I don’t see her very often. She very likely could have been living there for months. In this picture, she is out on her web “patio”, hanging out. I notice she does this at night sometimes, but usually she’s hidden all day. It’s interesting how her web is — it looks like a snowflake against the wall, and seems to exist mostly so that she can sit there with out losing footing and falling.
I’ve seen some males in my house. I think there’s a big “family” living with me.
Here’s some good pictures, if you want to put them on your website.
Best regards,
Denise Elliott
