The last dangerous spider species is the Brown Recluse (Loxosceles reclusa, photos here), depending on who you talk to and what range maps you look at. It is unsure if we have native Brown Recluses in Ohio; ODNR says there have been no verified specimens from outdoors, but that doesn't necessarily mean they aren't there. The very few that have been recorded in Ohio have been found indoors, most likely brought in by humans from elsewhere in their range, as they like to catch rides on furniture and the likes. Regardless, Brown Recluses in Ohio are very, very rare and highly restricted to the area around Cincinnati. It is important to add a note about their bite. Brown Recluses get a bad rep for their bite, which supposedly causes necrosis around the bite area. If you're seen photos of supposed bites, you know what I'm talking about. However, studies have found that only about 37% of Brown Recluse bites actually result in necrosis (the death of tissues). On top of that, studies have also estimated that nearly 80% of all "Brown Recluse bites" have actually been misdiagnoses. Most of the time it's actually MRSA, but can also be a host of other infections. The point is, Brown Recluse bites are incredibly rare due to their shyness, and even when they do bite it will most likely be harmless. If you ever see a supposed photo of a "Brown Recluse" bite, always be wary; it's more than likely something else. Another important thing to add is that doctors are not entomologists. Unless you watch a spider biting you, you can never be sure a wound was caused by a spider. On top of that, a doctor can never positively identify a spider species from a possible bite unless they have the actual spider.
Spiders do bite, there is no denying that. And in Ohio, unless they're one of the three listed here, you will be fine. Many spiders rarely bite, and it takes a lot to make them want to bite you. You have a better chance of being stung by a bee than bit by a spider. Most spiders bite when a human accidentally begins crushing one, like if you're putting on a shoe with a spider in it, or with other cases of making the spider feel in danger. Regardless, treat all spiders with respect and obviously be aware if the spider starts acting defensively, in which case they are probably to the point of biting.
Brechbühl et all, 2006) has found that this is not the case; color-matching individuals had the same success rate as mismatched-colored individuals. The actual meaning behind changing colors is still up for debate, but it most likely isn't for better hunting success.
here. Why are these known as the Nursery Web Spider? Like the others I went over in this post, this species does not build a web to capture prey; instead it actively hunts down prey. The females of this species (and the others in the family Pisauridae) will, however, carry around an egg sac (photo here). Upon the spiderlings nearing hatching, the female will construct a "nursery" made out of web and place the egg sac inside. After the spiderlings hatch, the female will defend this nursery in order to keep her hundreds of offspring alive.
So I ended up writing a lot more than I thought I would, but I just love spiders. I love how misunderstood they are, and they're just so amazing once you can get past the whole "ew a spider" issue so many people have. If you don't like spiders, I strongly urge you to give them a chance!
