Spider Photos - Button Spiders

Here's some photos of  Button Spiders as well as links to Black and Brown Widows and Redbacks.  In southern Africa, the button spiders (elsewhere in the world known as widow spiders) are the most important group of medical importance. Six species occur there, belonging to the genus Latrodectus of the family Theridiidae. The button spiders can be divided into the black button spider complex (4 species.) and the brown button spider complex (2 species.). The button spiders have round abdomens with slender legs of which the third pair of legs is the shortest. Their colour varies from cream to pitch black between species. The markings on the abdomen also vary from stripes to spots. In adult females the markings become less distinct. The patterns on the ventral side of the abdomen vary from having none to one with a distinct red hourglass pattern. Males are much smaller than females and the markings on their abdomen consist of red or white bands. The female button spider constructs her web, which contains a funnel-shape retreat on one side, usually close to the ground in bushes or under debris. The egg sacs are creamy-white and vary in shape from round and smooth to fluffy or spiky. The female frequently kills the male after mating, hence the common name "widow spiders". The female produces more than one egg sac per season usually during the summer months. The egg sacs are attached with silk to the side of the web. The spiderlings hatch after a week or more and one egg sac can contains more than 100 spiders. They disperse by wind and construct their own webs. They undergo between 7-9 moults before reaching adulthood and can live between 12-18 months. They feed on a variety of insects such as beetles and termites.

BUTTON SPIDERS

 The black button spider complex contains the following four species: Latrodectus cinctus, L. indistinctus, L. karooensis and L. renivulvatus and they are regarded as the more venomous group. Although no documented records exist of fatality due to black button spider bites, they have the potential to cause severe symptoms with small children and elderly people being at greatest risk. The black button spiders are black with red patterns on top of the body. The markings vary between species from stripes to spots. In adult females the markings become less distinct. There are no markings on the ventral side of the abdomen in adults. The egg sacs in all four species are creamy-white, round and smooth.

The brown button spider complex contains two species and they are regarded as less venomous: L. geometricus and L. rhodesiensis. They are very similar in appearance to the black buttons but their colour varies from cream, grey and brown to pitch black. The ventral surface of the abdomen in both species has a prominent red to orange hourglass marking, while the dorsal surface is covered with an intricate geometrical pattern in the paler specimens. A potential source of confusion with respect to the identification of these two species is that the most venomous species in Europe and America have the same red hourglass pattern as the two less venomous species found here. · Latrodectus geometricus is an introduced species and very common in Southern Africa and is usually found in built-up areas, especially around houses and outbuildings. They construct a funnel-shape retreat in dark corners with silk threads radiating outwards. The egg sac is characteristic in having a spiky appearance.  (Info: Ansie Dippenaar-Schoeman)

BROWN BUTTON SPIDERS

Reply: Be careful, this is a female brown widow  or brown button spider as you call them in South Africa, with her egg sacs - glen

Hi, I was wondering if you could help me identify the spider & egg sacs in the photo. I live in South Africa & have small children so wanted to find out if they were dangerous as I've found multiple egg sacs around the house. Thanks so much Stacey

Hi there. You will probably be able to help me identify this spider. Found it at my brother in-laws house and he reckons its the second one he found. He has 3 kids so he is a bit concerned. Can you give some information about it? He lives in Sybrand Park in Athlone Cape Town virtually next to the Lisbeek river. Thanks in advance.

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.

Reply: This looks like a brown widow spider but I can't see the underneath to see ifit has the red/orange hour glass which would positively ID it- glen

Hi Glen We realize that you may not know our spiders as well as thx Americwn ones and were wondering if you could assist in identifying this one. My son awoke to find this on his pillow in a hotel room in Bloemfontein, Free State Province, South Africa. It has a very hot and dry climate. We feel reasonably sure it may be a black widow since there appear to be many variants of them. We have contacted the Spider club here, they can't help us. Many thanks Liz

I also realized when taking the photos that this was a big one. About the size of my thumb. note also that when she was playing dead I could take a photo of her abdomen. I live in south Africa, Johannesburg. Cheers. Vaughn
