Well, if I had to guess I'd say it was Nuctenea umbratica, a common species in gardens and around houses - but the photo isn't too clear. See if yours looks like other pictures of N. u. on the internet
thanks for your reply.. it does look like that's what it is. I also found what looks like a dead female close by and have lots of baby spiders in the house but can't really tell if they are the same species. I read that Nuctenea Umbatica has a nasty bite and have a toddler and am due to have another baby in just a few days should I be concerned!!
Yes, I read somwhere that they have a nasty bite which surprised me because I've handled them occasionally (e.g. to relocate them after I've disturbed them whilst putting wood preservative on the fence) and never got bitten. I think it would be an unusual situation that resulted in a bite because they normally keep themselves to themselves. Personally I wouldn't worry - after all, we don't get too concerned about bees and wasps in our gardens and they could deliver a painful sting. But, if you think you might walk in to its web whilst it's in it, well try and knock it into a suitable container and relocate it - or get your husband / partner to do it!
Spider bites are of course uncommon and nearly always resulting from the spider finding itself in an unusual situation; this species is no exception. Although bite reports consistently describe the bite symptoms as quite painful nearly all that have been reported to us here result from the spider trapped between skin and clothing during the demolition of sheds, fences etc. As jaguarondi says apart from their when we demolish their homes they pretty much keep themselves to themselves.
