I was taking a close look at the substrate that's in a subspinipes terr. I saw really small, white spider-like things running around. Not much doubt in my mind they are predatory because of the way they move around. They are real fast. It was hard for me to catch one with my camera. They are only around a mm long. They run around like a Solifugid does. I think I've seen a pic of this thing but I can't remember the name. I think someone on the AB sent me a pic of one a long time ago and said they are good predator to have in your cages but I'm not 100% sure this is the same thing I saw in that pic I was sent, but I think it is. Anybody know what this might be?
