I can't see your images (it says I am forbidden/don't have permission to view the site), but from the description it sounds like the spider is likely a spiny orbweaver or spinybacked garden spider (Genus Gasteracantha).\n\nHere's some pictures of spiny orbweavers http://www.floridanature.org/species.asp?species=Gasteracantha_cancriformis\n\nhttp://bugguide.net/node/view/1982/bgpage\n\nThese species are harmless, even beneficial garden spiders that build typical spider webs to capture flying insects, including flies, mosquitoes and other nuisance species.\n\nThey do possess venom, but their venom is formulated for effectiveness against insects, and is not very potent against vertebrates, even if their bite was strong enough to break human skin (which it may not be).\n\nThey are not aggressive, and would only bite if the spider were injured or undergoing extreme harassment.\n\nUnless you were allergic to the toxin (unlikely, but remotely possible) the bite would probably be no worse than a mosquito bite, at worst it would be similar in pain and severity to a wasp sting.  Annoying, but certainly not life threatening.  The greatest danger would be infection caused by scratching the wound with dirty fingernails.

My daughter had a bite like that. I took her to the doc and he said it was from an (((((EARWIG))))) which is a bug that lives in trees and has pinchers in the front AND the back of the body so it can bite it's victem twice at the same time. The doc took a skalpel and cut open the pimple looking part of the bite to release the (((((POISON))))) and she was fine. A few weeks later I got bit on my leg by one while I was sleeping and I skipped the doc and lanced it myself. I have two little scars where it had bit me but I got the poison out and I'm fine too. The poison is a yellow/green color. Make sure you get it ALL out or you WILL have to go see a doc. Lance it till you see plain red blood without the yellow/green color.

LOL, you're talking about a Daddy-long-legs. It's a spider. They usually cluster up in massive groups around water during the summer. Go to a rest area in a park sometimes. They'll be millions of them.\n\nBut never fear, they don't bite, though they are poisonous but their fangs are too fragile for humans. Boys usually scare girls with them in school- I did! \n\nWarning: Don't smash them. They stink when you do!

Spiders.  Any and all spiders.  I don't have a problem with them being outside.  I agree that flies are gross and spiders eat them, so they do do some good.  But, spiders are the grossest.  Those eight legs, leaving webs everywhere, creeping around silently...YUCKY!!!!

It wasn't a black widow spider which are poisonous.They are dark black and shiny not hairy with white stripes on the leg. They have a red hour glass shape on the belly.I believe it might be just an ordinary jumping spider found in most homes non poisonous.

http://www.calpoison.org/public/spiders.html#1             http://images.search.yahoo.com/search/images?_adv_prop=images&imgsz=all&imgc=&vf=all&va=spider+bites&fr=FP-tab-web-t&ei=UTF-8                               The first site explains what spider bites look like and the second site has pics, I looked through several and I did not see one that lookied like what you are describing, are you sure it is a spider bite???  I will warm you the site with the pics is kinda gross!!!  but I hope it helps  Good luck, I would be curious to hear what it was, thanks!!!

It's hard to tell from your description (which doesn't include where you live, for example) what the spider might be. Odds are it is NOT poisonous, since there are very few spiders that are poisonous - if you are in the US there are two and one of them is not brown. If it is an orb weaver as you describe it is quite harmless and could be carried (loosely) in your hand to a bush without fear of being bitten.\n\nCan I suggest asking someone who is not afraid of spiders to take the spider out of your car (getting it into a cup is the easiest way to handle them without hurting them) and put it somewhere it will be able to live (not the middle of a parking lot).\n\nIt's interesting that despite your professed fear and hatred of spiders you've spent a fair bit of time examining this one and are interested in finding out what it is - all indications of a possible future arachnologist :-)

Sounds like moles, go to the hardware store and get more traps,  It is like a gian pouse trap you put it in their hole it catches and kills them.

More imformation would deffinently help. It is pretty much impossible to tell from the info you gave. What do you mean octagon spider? Does that refer to the web? Some helpful info would be the color, size, and shape of the spider, the shape, size, and location of the web, and where you found the spider (state, country, ect.). Any other information would also help. \n\nAnother thing to consider is that all spiders (other than a small, rare family) have venom. It is unlikely that they are very harmful, but again, I would need more information to say that for sure. Try a field guide (library is a good place to look) and see if you can find what kind it is, then research that one. If you want, post some more info here, and I will try to find it.

There are probably a lot of spiders that would fit\nyour description. More information is needed, such\nas where (geographically) the spider was seen, in\nwhat kind of habitat and at what time of year.  The\nvarious other answers mostly mention the garden\nor writing spider (Argiope), but it might qualify as\na large spider, depending on what you consider\nlarge.  Another eastern U.S. spider that sometimes\nhas a bright yellow mark and is smaller is another\nof the orb spiders, Verrucosa, which has a triangular abdomen and gets about a half inch long\nin body length.

i've never seen or heard of that but i'll guess a spider.

Any spider with a "fat round body" as you put it, is most likely a garden spider family Aranaeidae. These are the very commonly spiders that build large round "typical" webs between bushes, trees and on people's front porches. They are very effective at catching and killing large flying insects, so let it be, it'll do more good than evil. None of these spiders are venomous to people, most (even the big ones) arent even able to deliver a bite, so no worries, hope this helps!

Sounds like a butterfly caterpillar, or maybe a coleopteran larva. Could you provide a photograph, or a more detailed description?\nDoes it look at least similar to this:\nhttp://www.artcrawl.com/cgi-bin/artcrawl/ac.sla2?ai=4068*41290\nor this?\nhttp://www.ent.iastate.edu/images/coleoptera/curculionidae/0669.12cloverwlarva6in.jpg\nOr none of the above?\n\nI'll check back :-)

Maybe, maybe not. There are alot of insects (ugh) that are crawling or flying around that could leave the same marks.  However, if it even looks like it is starting to rot (for lack of a better word), PLEASE don't delay.  Get to the ER ASAP!!!!!!!I have heard that brown recluse spider bites aren't really noticed as you usually do not know that you have been bitten.  Do a web search on brown recluse spider bites.  I ran across a site one time - wish I could remember the URL.  It had pages and pages of Pictures of people that had been bitten by a brown recluse. They rate each and every one of them.  The ratings are from a 1-5. Of course 5 being the grossest things you will ever want to see.  You can also send your picture of the place where you have been bitten and they will be able to tell if it was indeed a brown recluse.  Good Luck.....

Doesn't sound familiar, but here's a link to an article about North America's "medically significant" spiders. take a look at the photos. If it's not on here, chances are you don't have to worry about it.\n\nhttp://www.royalalbertamuseum.ca/natural/insects/research/dangspid.htm
