Their prey is other arthropods and their webs are only strong enough for them. It has never been tested and they cannot break the skin of humans but there is no evolutionary need for an animal that can't even break human skin to have such powerful venom. Cellar Spiders are not believed to have secretions that are dangerous to humans. Then certain species of a type of arachnid called a harvestmanĪnd also the extremely beneficial cellar spiders. Originally it was crane flies (15th century Europe "Father Long Legs") There are three animals that have the nickname Daddy Long Legs Given his size the dose was probably so tiny to not be an issue. Felt nothing other a little tingle while he bit (and would not have noticed being bit were I not looking at him at the time). Watch his little fangs as they plunged into my skin. I had a tiny (maybe the size of 4 pinheads put together I just happened to see on my hand at the right moment. Otherwise they are going to avoid you and hide or crawl away instead of biting. The thing is getting them to bite you would probably require you to grab them with your bare hand. Those common yellow and black orb weavers you see in the garden all the time can bite, although the venom is not that toxic. And then there is others that can bite us, do have toxic enough venom in a quantity that will do something, but simply won't bite if they can possibly avoid it. A small spider might have a "potent" venom but can only inject it in such tiny amounts that effectively does little harm to large things like people (but would work fine on a tiny insect). I will add to others comments that there are an awful lot of spiders that can't really bite people for one reason or another be it small fangs that can penetrate our skin, or something else even though they might have a potent venom.
