Iridescence is quite common in insects and birds (and yes, spiders).  \n\nIridescence is when light reflects from *very* thin layers of semi-transparent material (think of the rainbows you see on the surface of a CD or soap bubble).  Some light reflects from the outer surface, and some penetrates a short distance before being reflected off an inner surface. The two types of surface are at a specific angle.  The wavelengths of the two types of reflection interfere with each other, creating new colors at specific angles.  (Incidentally, the word comes from the Greek 'iris', meaning 'rainbow'.)  That is iridescence.\n\nIn insects and spiders, the iridescence is caused by layers of something called 'chitin', the horny material that makes up the external skeleton of insects.  The layers of chitin are about a thousand times thinner than a human hair.

If it has been two days since you were bitten and there are no problems showing up you have\nnothing to worry about.  While almost all (not all)\nspiders have venom most of them have little or\nno effect on vertebrate animals, the poisons are\nadapted to kill insects and other invertebrates.\n\nYour description of the spider does not contain\nenough information to identify it.  One of the most\ncommon spiders shaped like a black widow is the\ncommon comb-footed house spider Achaearanea\ntepidariorum.  It is harmless.\n\nFor information on spider bites in general, with\nspecial reference to brown recluses, but also\nmentioning others, see an article titled "Bites of\nbrown recluse spiders and suspected necrotic\narachnidism" by D.L.Swanson and R.S.Vetter\nin New England Journal of Medicine, vol. 352,\npages 700-707, Feb. 2005.

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.

Sounds like a water strider:\nhttp://www.cirrusimage.com/bugs_water_strider.htm\nThese guys are very common in freshwater everywhere - even in salt water in mid-ocean. They might nip you if mishandled. \n\nIt might also be a whirligig beetle or another one of the aquatic beetles:\nhttp://academic.emporia.edu/aberjame/wetland/wildlife/wild1.htm

Are you sure it wasn't an insect of some type, like a stick insect or even a dragon fly? They can grow quite large sometimes. Either that or some bast@rd was playing a sick joke on you.....!\n\nsee the site below - there are some HUGE stick insects on there!!

Actually yes there are... here is one that is acutally called the Asian Centipede...\n\nPhysical Characteristics: Centipedes have long, flat bodies. Their trunks have many segments and almost all have 2 legs each. Adults in the family Scolopendridae have 21 or 23 pairs of legs, which are quite long and thick. The two last legs are very long and stick out backwards at the tail end of a centipede’s body. Its legs have joints and can bend. On the front of the head are two long antennae and under its head are two poison claws that end with a curved fang with a pointed tip. Centipedes may be as small as 2.5 inches long or as large as 12 inches long.\n\nMost Myriapods (both centipedes and millipedes) have tiny eyes, which can sense only light and dark, but cannot see color. Without eyes, their body surfaces sense light and dark. Tiny hairs on their bodies help them sense when something touches them. The antennae are waved around to smell and taste surroundings.\n\nDiet: Insects, spiders, earthworms, snails, and millipedes. Certain large centipedes eat small frogs, lizards, snakes, birds, and mice.\n\nBehavior: Much time is spent cleaning their antennae by wiping them with their mouths or front legs. When prey is caught, the centipede stabs the animal with its poison claws and injects its poison. The centipede then holds its prey and bites off one piece at a time.\nMost centipedes have long legs and can run quickly from danger and may even be capable of catching flying insects. Some centipedes can even break off some of their legs if a predator catches hold of them. The missing legs grow back the next time the centipede molts. Scolopendra species use their bodies to dig chambers in soil where they may rest for several days.\n\nYour friend is probably going to be ok.  Here is some information on bites from centipedes. \n\nDefinition    \n\nThis article describes the effects of a centipede bite.\n\nPoisonous Ingredient    \n\ncentipede venom \nWhere Found    \n\ncentipedes \nSymptoms    \n\nbody as a whole \npain in the area of bite \nswelling in the area of bite \npossible lymph node swelling \nskin \nredness in the area of bite \npossible numbness at the site of the bite \nHome Treatment    \n\nPlace ice (wrapped in a washcloth or other suitable covering) on the site of the bite for 10 minutes and then off for 10 minutes. Repeat this process. If patient has circulatory problems, decrease the time to prevent possible damage to the skin. A trip to the emergency room will probably not be necessary, but contact Poison Control just to make sure.\n\nBefore Calling Emergency    \n\nDetermine the following information:\n\nthe patient's age, weight, and condition \nthe identity of the centipede if possible \nthe time of the bite \nPoison Control, or a local emergency number    \n\nThey will instruct you if it is necessary to take the patient to the hospital. See Poison Control centers for telephone numbers and addresses. If possible, bring the insect to the emergency room for identification.\n\nWhat to expect at the emergency room    \n\nThe symptoms will be treated.\n\nExpectations (prognosis)    \n\nSymptoms usually last less than 48 hours. Severe allergic reactions or contact with exotic specimens may require more treatment.

There are 5 species of snake which "fly": Chrysopelea ornata, C. paradisi, C. pelias, C. rhodopleuron, and C. taprobanica, according to Robert Mertens' 1968 classification.  They are more correctly called Tree Snakes (Paradise Tree snake, Twin-Banded Tree Snake, etc.) \n\nThese snakes don't actually fly; technically they are parachuters (though some may be classified as gliders), so they can only move downwards through the air.

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!

The mosquito hawk is an insect that is vegetarian. They are very common in moist areas in north America.  They are quite large, almost 2 inches long.  Just a couple of days ago as I was sitting at my computer, one flew in front of my face, legs dangling right before my eyes. Startled me! They are harmless insects.  If you'd like to see a pic of one, and read more, check out this site:  http://en.wikipedia.org/wiki/Crane_fly

In general, Huntsman spiders are not regarded as dangerous. There are however reports of members of the genus Neosparassus (formerly called Olios) giving bites that have caused prolonged pain, inflammation, headache, vomiting, and irregular pulse rate. It is unclear under what circumstances these spiders bite people, but it is known that female members of this family are quite brave in defending their egg sacs and their young.\n\nHuntsman spiders is a common name given to the family Sparassidae (formerly Heteropodidae). These spiders are found in Australia, New Zealand, South-east Asia, the Middle East in areas near the Mediterranean Sea, Florida and Hawaii in the US, and quite possibly in many other tropical and semi-tropical areas.

I can't find anything, but I don't know what I'm looking for other than a black and yellow spider.  Here's a source which has some good pictures for which you can possible identify.  Check the garden spiders, orb weavers, and banana spiders.\n\nhttp://www.spiderzrule.com

Pholcus phalangioides\n\nThe Pholcidae, or daddy long legs spiders, is a large family with a worldwide distribution. In South Africa there are 3 genera; Pholcus, Smeringopus and Spermaphora. These spiders are harmless to man as their jaws are unable to penetrate human skin and the venom dose is also too minute. Spider specialists are often asked if it is true that, of all the spiders, the pholcids have the deadliest venom and the only reason there are no human fatalities is because of the small size of the jaws. There is no documentation on this. The venom is neurotoxic and is deadly to the prey. The pholcids, as well as other spiders, should be encouraged in the home as they control various insect pests such as mosquitoes, flies, fishmoths, ants and moths.\n\nmore info in the link below!
