This is most likely to be a White-Spotted Jumping Spider, otherwise known as a Daring Jumping Spider or Phippus Audax. They are not poisonous, although they will bite if they feel intimidated - in the same way as a wasp will sting when intimidated. They do not release venom that is harmful to humans. As with any insect bite or sting, they may cause an allergic reaction in a small amount of people.

These allergic reactions are not usually fatal and symptoms of a reaction usually consist of a lump around the area that was bitten at a greater size than a sting, nausea, headaches and a general feeling of being unwell. This feeling of unwell and other symptoms will pass but if you are concerned, see your GP. Following a bite from the Daring Jumping Spider, there is usually a slight pain for approximately an hour at the site of the bite. The pain should be minimal and will usually pass after this time. The Daring Jumping Spider gets its name as it tends to jump on its prey.

It is seen as being daring as it preys on insects that are sometimes much larger than itself. These include Black Widow Spiders. They are good at hunting due to their good vision. This is helped by their large eyes that point forward that they use to hunt out their prey. Here are some tips for identifying a Daring Jumping Spider: Usual size: 13-20 mm. They tend to move side to side, like a crab and also jump. Found in Southern Canada, United States of America and North Southern America, they are black with white spots and may also have white markings on their legs and have large eyes at the front of the spiders head (like a human).

A black furry spider with white spots that are located where the legs connect to the body just jumped on my about 15 minutes ago. I can't figure out what kind it is, but when I called my dad to ask about it.. He said that if you ever get bit by any kind of spider and are able to kill it (without squishing it) you should put it in a ziplock bag and put it in the freezer. He said that if your bite becomes a sore, you should take the bagged spider to the hospital to show them what kind it was and they will be able to identify and treat you much better.

If it looks like this its not only a harmless, but really a beneficial jumping spider. They've been known to kill and eat black widows and brown recluses in some cases. Their bites are not dangerous unless you have an allergic reaction. Very smart little buggers if you watch them enough though. We have quite a few in and around our house. They tend to do a good amount of watching you if you make too much noise and catch their attention. Rather neat really. If you cannot identify it for sure then I'd say leave it be or kill it until you can, better safe than sorry.

I live in Tx, breeding ground for most dangerous little critters, including spiders. I have found this kind of spider many times. They are black, kinda furry, range from pinky size to dime, and have 2-3 white markings on their back and under abdomen. I don't like spiders but have learned to tolerate these as they are harmless if left alone. I have looked them up on the internet and looked in books since I see a lot of them and they are a Wolf or Jumping spider. I am very aware as I do not want a Black Widow or Brown Recluse to get near me or my kids.

I have two huge bumps on my neck and the back of my arm from one of these things. It bit me over a week ago! Luckily, I saw it again yesterday (it has been crawling around on the chairs on my deck) and got it with some spray. It definitely left some big marks that are bugging the crap out of me!

I was in the back yard when Dad said, "Come here". And when I looked, there was a black spider with white spots. I was shocked and I went to go get a plastic bin, and now I'm studying it.  It turns out to be a daring jumping spider.

I have one my sister caught for me right here. I have it in a rather large jar with foliage and rain water. I just gave it a moth from outside and it jumped right on it =] I plan to study it and photograph it before letting it go.

I feel saddened that many people fear these non-venomous  & harmless spiders and feel the need to kill them. We call these garden spiders because they are so good for the garden and yard. They eat the "Bad Bugs" that destroy our gardens.

I adore jumping spiders of all kinds, and crazy to say even the dangerous ones!

All I hope for is that before killing a spider, please identify it online to be sure whether its harmless or not. If it is a garden spider, give it a chance to live and feed off those bad bugs in your garden!

I wish I could answer the question. I saw one as well yesterday - in Johannesburg. I didn't go too close but certainly close enough to see the white spots and it intrigued me. Poisonous or not I would love to know what it is... So will try keep watching this post.

I guess its harmful. I looked it up online and its a jumping spider so they say. Spiders don't scare me but when one was in my car then vanished everything that moved on my body like my hair or pants I freaked... I would love to know what exactly that spider is all about.

I just saw a Black spider with White spots on it's back , It was crawling down my wall from my ceiling. It was about half the size of a Pinky nail and I went pretty close to it and it didn't even move towards me or try to run away. I assume its harmless but its still on the loose so I will need to keep a close eye.

Well I suggest you keep away from the spider because the white spots indicate that it might be poisonous. There are numerous spiders like these in different areas, they are mainly sub-species of the larger spiders. Just don't go too close and you will be fine.

I was bitten about a week ago by one of these Black with one White spot on it`s back, Large eyes  The thing bit me on my backside It produced a large knot about one inch long and hard as a piece of wood, I took Amoxil & bathed the spot with alcohol & antibiotic ointment  the knot has finally gone down in size. The Spider is poison and can be very harmful to the elderly & children. If you have this spider in your house GET IT OUT ASAP check under the beds & if you play a guitar of banjo mandolin they like to hide inside of those as well.  Dan
