I'm needing some help. Recently at my aunt and uncle's property, we discovered this brown spotted spider w/ his backside deep orange and bumpy (like a brain). An interesting fact is that when either my aunt would pick him up w/ a stick or my uncle would wave his hand above the spider, it would rear up as though ready to attack. If anyone has information about the type of spider this is, it would be greatly appreciated.

While at work today my mother was talking w/ a co-worker about my new Polaroid mini printer, aka PoGo. My mom called me to ask how much I paid for it and where I got it. During the conversation, my mother was looking at photos taken by the co-workers daughter, as it turns out... the daughter has photos of the same spider!! This one was taken at their house on the front porch, the spider we found on Sunday was up in the foothills of the Cascade range.

Very strange.

Thank you all to those that help or have tips on where to look.

ciao,
Starrie
