Brown Button Spider
Latrodectus geometricus

The Theridiidae or Comb-footed spiders is a large and diverse family represented by 15 genera in South Africa. They are nocturnal, web-living spiders. The family is best known due to the notoriety of the genus Latrodectus, the Button spiders, also called Widow spiders as females often consume the male after mating. There are 6 species in South Africa.

The very common species, Latrodectus geometricus, or Brown or Geometric button spider occurs around every home where I stay, outside under window ledges, behind drain pipes, under wood piles etc.

Although its bite can sometimes be troublesome, it is not life threatening as is the case with of most of this group. However, Latrodectus indistinctus, or the Black Button spider presents a serious problem. Its venom is neurotoxic (affects the central nervous system). Bites used to be very common during the manual harvesting of corn but these days with mechanised harvesting, bites are quite rare.

Button spiders are very timid, usually retreating when disturbed or dropping to the ground and playing dead. Bites result from handling or when they are trapped and squeezed.

The main symptoms of Latrodectism (Button spider envenomation):
* sharp burning pain at the site
* pain spreads to lymph nodes within 15 minutes
* severe muscle pain and cramps in an hour
* tightness in the chest
* difficulty with walking
* anxiety, sweating, fever,
* slurred speech, nausea and headaches.

If this does not give Callie nightmares I do not know what will! :)

Less than 5% of untreated cases result in death, usually as a result of respiratory failure. In fact, there have been no deaths from button spiders in the last 4 to 5 decades. Those more severely affected are children (smaller blood volume) and the elderly who might suffer respiratory or heart failure. All Latrodectus bites should be treated and monitored

I love the pose of this spider I captured. I could have been sharper, I know. But the pose (and my love for spiders :) was the driving factor in my decision to post it. Hope you like it.

Looks like jumping at you Gerhard :-) Great pose and composition, I like orange sign on its body. Very good note, too.

Just great. The pose is menacing and all the detials are great. I love these as you know and I love this one.

Great job with your lens and extension tube, Gerhard. I intend to buy such a tube too. The effect of the blurring of the web around the spider makes it look a translucent glass; a very nice effet IMO. Bravo!

Well, at least this one remembered to shave its legs before posing for a photo, ours never do ;-))
Interesting critter, sharpness seems ok, and only the tips of the two top legs fall outside DOF range. Clean bg, good light.

This is an awesome shot, Gerhard. Great looking spider, but after reading your terrific note, I don't think I would want to get too close to this gal!

Great shot with very good point of view. I like spiders too but do not have any pictures of it. TFS.

Definitely a big nightmare Gergard. Spiders and moths I try to avoid. Please don't export it here.
Good capture on its web though. Well done.

Thank you Gerhard I showed it to my wife a she ran away :-)

Great shot, what's the white spot above the spider.
Well done
TFS.

The Doom, the Doom, my kingdom for some Doom - these are one of those guys with the disgusting fat body that splats all over when you squash it.
They are fond of the bottom of window cills, and I just suffered some goosflesh thinking of cleaning them out.
That said, this is a very good picture, Gerhard, TFS, goos POV, compo and the hourglass is clear. 'n Giftige foto, mooi man!

Great one Gerhard, these are my favourite subjects and I still have to find some to post on this site. That will be my challenge this year. Many thanks for this one and it really is a scary one to see and unless you know spiders then my guess would be keep well clear. After seeing these films of jumping spiders who knows ;-)

Once more, congratulations.

I should not have looked this shot so late at night, this is truly what nightmares are made of. The sharpness is excellent and this composition is really scary.

Very well done and thanks for posting.

Great shot, looks like he's going to jump out at us. Pity its not super sharp, but a well composed image anyway.
