Jewel spider, Crab spider, or, as I know it, Thorn spider.






I saw the post with pictures of these guys, but I thought that one which actually includes some info about them would be ok. I first discovered these guys after moving to Florida and finding them all over my back yard, I had no idea what they were so, I searched the internet and the library, I'm sorry I can't cite my sources, it's been a while. First off, like many spiders, the females are larger than males, the males die within a week or so of mating, and the females shortly after egg laying. Males are capable of web building, but they don't actually do so, and females build a new one every morning. (Considering the size of some of the webs I've seen, as large as three feet across, this is a bit impressive.) I recently witnessed one rebuilding her web, she was eating the old one while building the threads of the new behind her. They also tend to weave large "fuzzy" areas into the web as a warning to birds so that they don't fly through them and destroy them. The real thing that makes them WTF-worthy to me though isn't they're odd and beautiful appearance, it's this. They hum if you desturb their webs. I didn't really believe it when I read it, so of course I went out to find one to pester, and I'll be damned, they do indeed hum. It sounds a bit like a cicada, but no where near as loud. They are not poisonous, nor are they really good bug catchers compared to other spiders, their size and shape tend to make them clumsy and ungainly, as well as slow. Bugs usually tear out of the web before the spider can get to it, or, the spider itself accidentally lets them loose trying to wrap them. This is all I can currently remember about them, but really, the humming it the coolest thing.
