Hello,
First off You have Yarrow spiny aka mtn spinys. They love shipping crate for the spiders that acumulate in those areas, especially if the crates are left outside for any amount of time. Second congradulations on the litter of spinys, but I would sugest you move them to anouther terarium or you may find out that you no longer have as many as you thought. A fellow herper brought some back, they had babies then before he knew it there were no more babies left the adults ate them all. Third and most importantly your cage is to hot, where they come from is the mountains of arizona. Average temp is in the 70's to low eighties. What I did for my breeder cage of yarrows is I added forest floor material for the base, a couple of old branches you would find on the forest floor or grape vine works well, some granite slabs stacked for hiding. They enjoy being misted with water, do this at least twice a week. For the light fixture I use a aquarium light fixture with a grow light for a reef tank. The light it provides is what they need (natural full spectrum).And the cool warmth it provides is all they need, especially when kept in a climate controled house. If they are kept in a cold room, then just add aluminum foil to the top of the screen that is not covered by the light. The non responsive yarrow might be fried, if he doesnt respond after you change the set up, then you know what up. I breed the yarrows and am looking for more to finish out that project. If you decide to part with any let me know. If you would like email me and I will send you some detailed info on them as well as the blue spinys with pics to go by.

Hope this helps,
Gary C.
