It is the marbled golden orb weaver.
maybe it's a black widow?
This is most likely a common garden spider. They typically are described as black and yellow, but the yellow markings can appear orange at times.
This isn't much info and someone may expand on this anwser, but his spider might be reconized by the name of a Black and Yellow Argiope.
Black widow
A red and blue spider is called the Red-Headed Mouse Spider and the scientific name is Missulena Occatoria. These spiders are considered dangerous because they are known to produce high amounts of toxic venom.
It's my understanding that the color of the markings on a black widow are by and large red, but can appear in yellow, orange, and white. I would regard that spider as a black widow for safety's sake.
black widow No this isn't a black widow...their red or orange markings are on the spiders belly since Black widows hang under their webs. The best guess is a jumping spider if the markings are visible when the spider is walking around. The Australian Redback Widow is the exception to the rule, it's markings as it's name implies on on the back.
It could be a black widow spider if it is small and thin-legged with a shiny round black abdomen and red markings under it. If it's fuzzy with a red spot on it's back, and the front part of the body is more-or-less the same size as back part, then it's a black jumping spider.
Spider wasps have curled antennae and black wings but can also have different color markings such as red or yellow . The female spider wasp will hunt spiders to feed it's larvae.
It could be a wolf spider which has bites are are painful but not poisonous. There are many common house spiders that have these markings.
