Wondering what this patch is on the back of my large Rosea. Possible premolt maybe? Yet she's still eating like a monster. But she is digging alot and webbing huge clumps of dirt around her enclosure, near the burrow. But as far as the patch I looked and didn't see movement like possible mites. Just a patch she's had since I purchased her. Sorry for bad pic. Camera isn't worth a darn.
