Spider Photos - Brown Widow Spiders

Here's some photos of  Brown Widows.  Spiders of the genus Steatoda belong to the spider family Theridiidae, or the cobweb weavers. Also known as Combfooted Spiders, this family includes a number of well known arachnids, including the American house spider, Achaearanea tepidariorum, and the redback and widow spiders, Latrodectus spp.. Steatoda spiders are found throughout the world, in both temperate and tropical climates. They are small to moderately small (3-9 mm) spiders with oval abdomens; they may be reddish, brownish or black, with most species exhibiting a white band at the front of the dorsal abdomen which may resemble a collar. Brown widows are easily confused with the harmless cobweb spiders so not all ID's below may be correct!!  For other types of spiders please select a section:

BROWN WIDOW

The brown widow spider (Latrodectus geometricus) is native to South Africa and was first discovered in the United States in 1935. This spider is also commonly known as the grey widow, brown button and geometric button spider. It is venomous and has a neurotoxin like that of the black widow. While it is true that brown widow spiders are highly venomous to their prey, they are very timid and rarely bite humans; when they do bite, they injects less venom than the black widow, so the widespread fear of a bite from this spider is unwarranted. The brown widow is one of five United States species of the widow family. The Brown Widow varies from light tan to dark brown or almost black. It has markings of black, white, orange and brown on the back of its abdomens. It is easily identified by its typical mine shaped egg sacs. Black widow egg sacs are round and smooth.

Reply: Be careful with this guy, it looks like a brown widow so be careful as its bite can be dangerous. However on searching more, I found that there are no recorded sightings of them in Sydney and they are rare even in Brisbane. In fact you can record a sighting of one on the link here. It could also be an immature redback as they look similar in their early life. The best way to tell the difference is by the egg sac which is spikey in a brown widow. But if this is a male (probably not though) or immature, it won't have made one yet  - glen

Hi again Glen Just wanted your expertise on a little fellow we found hanging out around our front door here in Sydney tonight. His body shape was what stuck out immediately as a red back however the colouring of white, brown and orange is unlike anything we've seen. As you can see by the brick mortar he was about 1.5 to 2cm and banded. Quite pretty really with such unusual colouring. What do you think it could be? And if you do know, is it dangerous? Feel free to use any of the photos we send you however you like too by the way. They're only taken with an iPhone5 but I try to get a clear shot for you haha! I spoke to you about a month ago about the wolf spiders that have taken up residence in holes on our front yard... they must love it as there are now even more holes. Eeek! Thanks in advance for your help again.

Hi there, Recently I found two different spiders in my apartment in Redlands, California. I do know that the one with the smaller body and large sensory organs is a male, but I do not know what type it is. The other appears to be a female because of the large body and small sensory organs. It would be appreciated if you could shed some light as to what type of spiders these may be. Thank you for taking the time to look at the photos! Sincerely, Danielle M. Redlands, CA

Glen, what a great site you have. My wife has come to love collecting black widows since we found one on our porch 2 years ago and has since become and "expert" with spider identification. However, since the black we did find was the only "black" widow, I think she is clouded by wishful thinking. I have not seen any smooth egg sacs but I have seen plenty of spiky ones. We kept our "Billy Jean" for nearly 2 years before she died after a move to our new home and she has been on the warpath to find a replacement since. Everything she finds is absolutely tiny, and what I believe to be brown... Please tell my wife we have brown widows not black so she can leave me alone about catching them. Thank you, Jason

Dear Glen I live in Pretoria, South Africa, and have spotted an interesting-looking spider that I hope you can identify for me. The first two photos are the ones I took (the one of the spider busy covering her eggs in a sac). I found the second one on this website: . It looks slightly similar to “mine”, but I can’t be sure. I had a brief look at your website but could not see any photos that looked similar – so, seeing that you provide an email address, I decided to write to you. Thank you in advance for letting me know what kind of spider it is. Also, if you could let me know a bit about the spider, I would appreciate it – specifically, whether the mother needs to eat while she keeps an eye on the eggs. I ask this because I would like to try to get her and the eggs into a jar so that I can observe them. I live in a block of flats (apartments), and the spider is in a public area of the block, where there is a good chance that someone might see her and kill her. I would like to prevent this and, at the same time, to learn by observing the hatching process. But if she needs to eat and I have her in a jar, I might kill her myself despite my good intentions. J So, any information you could provide would be useful. Sincerely Kirsten Eksteen. PS: most of the eggs that I saw when I Googled “brown widow spider eggs” are covered in “prickles”, whereas the one in my photograph is more or less smooth; but there were also a few smoother ones on the Internet – so the matter remains inconclusive so far.

Thought you might like to show a couple of these I took last summer. This is in the pool area at back of house. We don't have many (if any) Black Widows in Florida, but man we have Gray Widows going from almost pure white to very dark. Gray Widows are differentiated from their more famous relatives in a lot of ways, the easiest is that the Eggs of the Gray Widow have "spikes" or "volcanoes" all over them, wherein the Black Widows eggs are smooth as silk. I have a number of other pics if you find these interesting. They are all in the 2.5k x 3.0k range so I could get a great look at the eyes etc. I shrunk. these to keep the ISP's happy.

Michael's Reply: I viewed a lot of Brown Widow spider images online and believe that this is exactly what it is.

19 November, 2011:
Hello, I live in Bahrain. I noticed a lot of these spiders around the outside of our house. You should be able to zoom in for a fairly close look. These pics don’t show the back of the spider, but they roughly have the same round shape as a black widow though smaller. They are basically grey in color to slightly brownish. The webs are not symmetric and are typical widow design. I saw a very small brown spider inside the tunnel portion of one web and I assumed it was a male. I will have a macro lens in a couple of months so I should be able to take some better photos then. Hopefully, these will be enough for quick ID. Best regards, Michael,  - Saudi Arabia

Hi I found this spider on my garbage container wheel. It seemed to have two white dots on the back of a dark spider. Do you know what kind it is? We have a lot of spiders inside and outside. They seem to somehow come in. I know black widows but generally I carry most outside as I see them. It seems the brown recluse is similar to many spiders though. How do I know what to kill and what to carry outside And be safe?

Reply: That's great to hear that my site has helped you overcome your fear of spiders!! This little lady is not a black widow though, she is a brown widow from her spiky egg sacs!!

!13 March, 2011:
Hi Glen! Years ago, I was so afraid of spiders I would probably say I was a borderline agoraphobic. But, we live on the east coast of South Florida and seeing a spider is almost a daily occurance for us. When we moved into our house, my husband convinced me that killing a spider in your home was bad luck unless it was a danger to you or your family. Plus we have a daughter who is now 7 years old and I did not want to pass on my fears to her. So I found your website and my fear has turned into a complete fascination. Back in 2005 I sent photos of a huntsman to you. We found it after one of the hurricanes in 2005 clinging to one of our screens. This time I have attached a number of photos. Most of them are of - I can't believe I am about to say this - the most beautiful mommy black widow and her egg sacks. I couldn't take enough photos and she patiently posed for them. I found her in the corner of one of our screens. I wish I had put something in the photo as a size reference but I am not that fascinated nor do I think she would have been that patient. But I will say she was BIG for a widow. The other photo is of a spider I found outside of our screens and it had a massive web. I haven't had time to really look it up, but I think the photo is pretty cool. Feel free to use any of the photos as you'd like. If you know what the second spider is, I'd love to know. Thank you for all the work you put into your site! All the best! Sandy

Hi Glen, We are overrun with brown widows, finding them hiding everywhere. They have even taken to living boldly on the outside of our garage doors…in mid-day sun. They nestle in the corners of the molding. I have numerous photos, and thought I’d pass several along. I’m technically challenged, and can’t figure out how to get outlook to allow me to send more than 3 pics at a time….so will send several notes. Sorry! The picture 0014 was taken about 8 years ago when my boys were small. I collected a bunch of them one fall, and used them as “show and tell” for several schools. I felt compelled to let teachers and students know what they were, since they live all around the houses, under pool chairs, etc. Our local paper gave some mis-information, which prompted my crusade. We fed them crickets, and dutifully cleaned their temporary homes. It was amazing. They ALL spun egg sacks in the jars. Holly, Charleston, SC

So why all of a sudden am I seeing all these spiders around? I'm getting the ickies. Captured the brown widow today. I'll try to photograph before disposing of it . The attached coincidently just appeared on our screen porch. I find this very disturbing. These anols dine on spiders, so I can only believe this small, young one must have jumped into the web after the spider. I do not think a bigger anol would have gotten stuck. The discoloration of the anol's head and tail, as well as other unusually colored patches suggest to me that this spider has a nasty venom. Am I right about that? Can you identify it? I have another picture from today that I'll send in another email. Regards, Mike

Glen: My interest is in photography, not spiders, but they make an interesting challenge at times. Do you want to receive all these pictures people send you? If so, I'll keep it in mind if I get some interesting ones, but if you have enough, I won't bother. Speaking of bother, I wonder if you wouldn't mind telling me what this bugger is. I can't seem to get a decent picture as it is inside a web and retreats inside the faucet when disturbed. Mike

Reply: The hour glass shape appears similar to others on this page but its pattern is somewhat different. It is certainly a male - glen

15 August, 2010:
As there is an, apparently, fattened hour glass on the ventral side and large pedipalps. I'm tentatively categorizing this as male Latrodectus geometricus. However, the pattern and coloring of the dorsal-side of the abdomen, and the shape of the 'hour glass' appear perhaps somewhat unique. Thus, confirmation or otherwise would be appreciated. The very best. R.J.

1 August, 2010:
I am sending 9 images in all. All are Brown Widows except for the first one. It's actually quite amazing how in some parts of Los Angeles (if not all) Brown Widows seem to have displaced much of the Black Widow population. 2 years ago, Black Widows were everywhere and every now and then I'd see a Brown Widow. Since last Summer while Brown Widows are fairly easy to find in large numbers, Black Widows have become a rare find. -- I'm no expert, but I'd imagine that the Brown Widow's tendency to run for cover while the Black Widow's tendency to stand its ground could explain that. cheers. erico.

Glen, I took this picture of a couple of spiders I saw at my house. The classic hour-glass on the abdomen lends me to believe they are widows but I have only seen black widows. After looking up on the web I have seen several widow pics. Is this spider an immature black widow male or female or is it a brown widow?

Hi I took this picture of a spider unsure of what it is. I it found while I was swimming in my pool. My dad thinks that it is some kind of mutate black widow. Even though you can't see in the photo, the colouring of the spider is that of halloween colors: brown, black, orange and white. The hour glass is orange and down the middle of the abdomen there is an orange stripe. My dad killed it before I could catch it or get a better photo. My name is Lindsey, and I live in Buckeye, Az.

We found this one clustered in a colony with others just like it outside hanging out on our aloe cactus plant. Pretty small, only maybe  1/2 inch total.

Hi..just thought I'd drop you a line and see if you've ever seen or heard of an albino redback? I have a spider on my balcony who appears at night that seems markedly like a redback, only white. It has an identical body shape and the same sparse erratic web as a redback, and some markings underneath which may fit the hourglass distinction ( I have plenty of redbacks around this house). I've been trying to get a decent photo of it but so far can't get a great shot - I don't want to disturb it too much just for 'science' if you know what I mean. I've been searching the net the last few nights and your site seems to be well informed so I thought you may be able to shed some light for me. I've stuck in the photos i've taken anyway so you can have a look. Regards, Marc

Hi, my name is Joey DiPuma. I live in Florida. I took these pictures and figured you wouldn't mind seeing them since you are obviously a great fan of arachnids. The first one, I think, is a Black Widow however the brown stripped legs make me think it could be something else? In July I cut my foot open and had to use crutches for roughly 3 months; I had to shower by leaning on a plastic lawn chair to avoid getting my foot wet. The first night, for some reason before I actually got into the shower, I flipped the chair upside down and sprayed water on it. This spider came running out as soon as the water went into a crevice the folds of the chair made. Needless to say it creeped me out for about, forever. I do remember seeing a red shape on its back but i can't recall whether it was the hour glass or not.

Hi Glen, Great site, I've learned a bit just from visiting it for a few minutes. I found some black widows and a few of these other spiders I'm unaware of the type around the outside of the house. It looks like they could either be a "Red-back" Black Widow or a Steadota. After reviewing the photos on your site I can see others mistaken the two as well. I couldn't see the bellies of the Steadota photos, that made it hard for me to figure between the two - though the belly of this spider seemed to match the Red-back's. Btw I'm in Southern California, not sure if the red-backs are even found out here. Thanks for any help, I know you're a busy person Blu

Hi, Glen -- interesting website! I couldn't find an identifying pic on your website of the attached spider; what might it be, do you think? I live in Boulder, CO, and found this spider, maybe a bit less than an inch long from tips of legs to tips of legs, under my BBQ grill yesterday. Any ideas?
It was, interestingly, found right after we saw a black widow spider run from the grill as we too the grill cover off. (We killed the black widow) This doesn't look like the male black widow, or is it?  Thanks. Jane

Reply: The spider of 21 August from Roy is indeed a brown widow spider, L.geometricus. Note the tufted eggsac--a dead giveaway for brown widows. Despite the name, not all brown widows are actually brown; the species is highly variable, and a coloration anywhere from nearly white to nearly black is possible. Markings are more important than coloration: the ( at least approximate)hourglass marking, the leg banding, and the type of abdominal dots/ eye-like markings are what to look for in addition to the widow-like body shape. For instance, all of the spiders in the pictures below are of L.geometricus:

Notice how they may change color, but they all have the leg banding, an hourglass, and roughly the same type of markings on the abdomen.  And the
eggsac of L.geometricus. I really don't mean to come down like a ton ofbricks--L.geometricus is a ridiculously variable species, and can be quite difficult to identify. However, if you look beyond coloration to things like patterning and markings, how the spider is shaped, and the appearance of its eggs ac, then despite how whacky their coloration might be, you can still discern L.geometricus from the other widows, and other cobweb weaving spiders. Again, I'm not trying to be harsh or belittling, I just noticed that you had an brown widow listed as not being a brown widow, and I wanted the give the fella the right ID, show you why it was that species, and help you to ID these crazy critters in the future. Have a great weekend! Nathan.

Love your site, its great! there were several email addresses, I hope this is  the one for sending in photos. These were taken in La Mesa,east county area of San Diego,CA.It seems to be  a "brown widow" I have never seen a spider like this here and I have been
aware of the native fauna since I was a
child. Note the spiky egg sack. thanks
Roy.

Reply: Black widows and brown widows belong to the family of comb footed spiders, Theridiidae, and several other of this family look remarkably alike - the false widow Steatoda nobilis, being one of them. If they have spikey egg sacs they are brown widows. Read info above. Click photos below for a larger view.

I live in cape coral Florida and we have our house spayed once a month but it doesn't seem to stop these girls. On my front porch there are 4 plants in ceramic pots and theirs always 5 or six in each plant and underneath the chairs with round egg sacs with spikes are these both brown widow spiders? I can only identify the darker one. what is the white one with the little spots on top of its back.  can someone tell me what it could be! Thanks  John Gabriel

Glen, Thought I would share a couple of photos I have taken over the last few days where I live in West Central Georgia, USA. Your site has been so helpful in identifying some of the spiders I have encountered recently. Attached are photos I took of a Brown Widow, Black Widow, and a Green Lynx. I hope you can use them. - Jason

Hi i know nothing about spiders, but i think ive recently captured a few brown widows around my house in Cyprus (mediteranean) that are now in a jar under scrutiny. Ive also just caught an unusual looking spider that resembles exactly that of a black widow only it does not have the red hourglass underneath...instead it is jet glossy black with a bright red stripe about 1mm thick on it, the stripe goes from left to right in a straight line if you were looking an the spider head on, about 7mm long like a long thin rectangle. I wonder if you could elighten me on what i have caught. I am an english tattoo artist running a studio in Cyprus and have tattooed the black widow before so am familiar with the spiders characteristics. Tonight checked the net and am possitive the other is the brown widow, i crushed 6 egg sacks in my phone box cupboard which looked like spiky war mines like you got in the sea and were creamy white coloured....i would rather these werent in the same house as me in case they hatched 1000's of young ones as i believe they can be nasty.

I love your spider site! Here are a couple of spider pics I took around my  house. Widow_scorpion_081204c.jpg: This juvenile female Black Widow set up  housekeeping in our upstairs shower. We eventually had to relocate her so  she wouldn't be washed down the drain or killed by our cats. Before we
did, she caught and ate a bark scorpion.

Here are some pictures of a Brown Widow I caught in St Petersburg Florida.
We have them all over the place now.

This is a Brown Widow (L. geometricus). It isn't as poisonous as the Southern Black Widow, but I'd still stay away. It is commonly found in tropical states of the US. Paul Day - http://www.losingmylycosa.com
