That's interesting, Siobain. We have quite a few at home - all outside thank goodness. Next time I see one, am going to check. Tummy or back.

You should also check the egg sacks as the Black's is a lot smoother than
the Brown, they are not aggressive, however, I was bitten by a Brown a
few years back, because of my own stupidity I have to say...walking around
in the garden at night without a torch, I walked through a web without
thinking much about it, climbed into bed and suppose I squashed it a bit
so it bit me on the leg, lucky for me it was a small one but really not a
pleasant experience.
:| Always walk around with a torch now.

Thanks :thumbs_up:. I think we have brown BS - the egg sacs are spikey.

Thanks Siobain! :thumbs_up:

I'm still going to find a Black one and maybe I should look for the smooth egg sacks first! :thumbs_up: :thumbs_up:

Yes, as the others mentioned, the egg sack is the definitive way to make a positive i.d.

Hi Folks

We do not get Black Widows (Latrodectus mactans) in Africa. We do getr Black button spiders which are a different species, different behaviour and very different venomosity. Black button spiders are extremely rare in the urban environment. They prefer the natural environment, away from habitation. Our black button spiders DO NOT HAVE A RED HOURGLASS (excuse me for shouting). Our Brown button spider are common in the urban environment and are a fraction venomous as the Black button Spider.

Another snippet of info is that there are no medical records of anyonw dying from a Black button spider bite in Southern Africa in the past 50 years.

If you find a spider with a red hourglass marking under the abdomen it is a Brown button spider.

Kind regards
ScorpionKing

Brown button spiders are cosmopolitan. They occur just about everywhere. Which species of Brown button spider are you working on?

What is the focus of your study?

It's Latrodectus geometricus, the brown button spider.

As far as I know, there is only one brown widow spider in the Cape Town area, Latrodectus geometricus. It has a distinct orange hourglass pattern on the ventral side (underside) of the abdomen. My project is testing the thermoregulatory property of the silk projections on the egg case. I am aware of their ubiquitous distribution, but need to find some in a remote, safe area because I will be measuring temperatures overnight with expensive equipment :)
