spiders in Georgia

I found a spider in Ellijay, Georgia that lit up at will like a firefly, glowing white/ green. I was on the deck of a cabin we were renting. This spider was huge and hanging from a wooden beam. The body was about the size of a quarter. It was all black with a very white design on it's back. Like a boomarang with wings, the best I can describe it. It starting lighting up as we walked inside the house. Intermittently. Very bright light. Not glowing, a light inside. Freaked me out! My husband and I have never heard of a light up spider. Can anyone out there identify this spider? Kim

spiders with lights
I have never heard of a spider that has any ability to create light or glow. I wonder if it could have been a firefly on a spider or near a spider?

Some large black and 'white' spiders found in webs in GA that I can think of are Argiope sp., Araneus marmoreus
or maybe Neoscona domiciliorum. If we are a little looser on color maybe something like Nephila clavipes.

See examples here


 
Luminous predator...?
Maybe it's a larval predator or parasite attached to the spider?

 
It looked like your picture o
It looked like your picture of your bottom middle spider. And there was no way it was anywhere near anything else. it was hanging from a web 3 feet away. It lit up at will. Plus fireflies light up orange/ red. this was white green like his markings. Soooo weird!

 
lighting up
I have spent some time since early this morning after being bitten 4 times. I have had this problem since late last week getting bitten while I have slept. A couple bites a night. Except last night it was more. It is not bed bugs in case anyone is wondering, been there before and that is truly terrifying. I haven't seen the tiny holes yet from last night but on the previous ones, I have seen the holes that would indicate a spider is the culprit.if it isn't enough that I am so scared of spiders, in the middle of last night, after being bit four times I got up and stood there and was getting ready to rip my jammies off when I noticed that there were flashes underneath my sleep pants. For me the first thing I thought of were flashes, but the same as lighting up. Like a lightening bug would. I freaked out and took it off. Turned the light on and pulled them inside out. I didnt see anything and can't identify what it looks like. I am in Missouri. But as soon as the swelling goes down I will look for the tiny bite marks. I tried googling though of what kind and your question and sighting is the only one so far that is anything of the same.

Where I come from we call this (flashes of light in our clothing) "static electricity".

Spiders do not feed on blood, nor is their bite an effective defense against sleeping humans; so why would you assume that spiders are biting you?

Why do you rule out the "truly terrifying" -- i.e. bedbugs, which, as it happens, DO feed on human blood and are active at night...

not bed bugs
I am ruling bedbugs out because I have been there and I know the patterns of them as well as the actual blood sucked spots. They also suck in lines. Not just a bite here and then a single one somewhere else. Unfortunately I have too much knowledge of bedbugs. As far as spiders and what I experienced this particular night, it has the markings of a spider. The holes from the bites. Definitely a spider. No electricity sparks as pretty much anyone if not everyone has experienced a little electricity spark in their lives and knows how that feels. The lighting up was a single one at a time. I assure you its definitely not that. I live in a house that has a well wooded area in the backyard and I have roommates as well. We are all dealing with spider bites at this time.

 
Go hunting
Maybe you should consider a hunting expedition & thorough cleaning. Collect all the bugs/spiders you find and post their images here for ID.

Also the static electricity that is caused by clothing & bed sheets does not usually give you a shock.

 
Neoscona domiciliorum
That one is Neoscona domiciliorum.

That is really weird. Thanks for sharing, sorry we don't have an answer for you.

Actually my husband says it's the bottom left orb-weaver. Lighting up though? too weird!

Maybe the spider swallowed a firefly? :-) (It's getting hot down there, isn't it.)
