Advertisement I will probably be getting a small colony of these guys soon. I've noticed there seems to be a lack on info except for bits and pieces from people who keep WC specimens in their area. Because of this the information varies. S. Donensis is named after the superstition mountains where they were first collected. The area seems to be very dry, but varies in temperature throughout the year from low 60s to high 90s (probably higher). Despite the climate, people claim they like it moist. I also haven't found a straight answer about substrate. One keeper uses clay and sand, another coco fiber. Apparently thats because they are found in a much wider range than just the superstition mountains in arizona. This variation probably means they are a hardier species, but I do want them to thrive. Is a heat pad recommended? I would probably use my soil/coco/leaf litter mix for substrate, but in my experience it dries out really quickly when I use a heat pad on small tubs.
