hah, you sound like me a few years ago, when I found a Jewel Spider in my back yard. They look scary and they're HUGE (well, they're the biggest I've ever come across, anyway... Technically, they're on the small size in the spider world, lol). But I did research and became absolutely fascinated by the spider, and when she laid eggs, I danced! And then I cried when she died. But the following August/October, when I found another Jewel Spider, in a different spot, I danced again! The descendents of that first spider have come every year, and this year, there were two, maybe three! Two were in the garage (one female, one male; and I want to add, the female had a huge, gorgeous web, but the male at the other end of the garage, had this small, messy one, lol). There was another sighting of a Jewel Spider hanging right out side the kitchen window, which scared the living daylights out of me because I wasn't expecting it, but that was the only time I saw it. It may have been the female that was in the garage, since she disappeared about the same time that Kitchen Window spook showed up, but there's no way to tell. I saw it hanging out there, went out to see if I could get a closer look a few hours later, but she'd disappeared, and I haven't seen her since.
But next year, there'll be another one hovering in the corner just outside our front door, or by our back door, or in a nook in the back gate, or in the garage. Once I learned that Jewel Spiders are harmless (and eat black widows and brown recluse spiders, lol), I fell in love. They're still creepy, but man, they're equally fascinating to watch.
