Here you go:
This t is also a desert sp.. You can see the white bumps built up. They are mites, and they hang there because that is the only place in the cage where they were able to get some moisture to complete their life cycle. The moisture came from the ball of crickets that was collected there once a week. The mites most likely came from that too. I still have this T, and she is now mite free. I just removed the molt immediately from the cage with most of the mites still on it, and rehoused her when she hardened up a bit........ If you don't see something like this on your rosie, she probably doesn't have mites. There are some sp. of mites that act as parasites on the t, but they are rare, and usually come in on wild caught t's. It sounds like you have had this t for a while so I think you are probably alright there. If you can get a pic of the abdomen I may be able to help you with that. I tried to find a pic of what I think you're seeing there, but I don't have one........... If your rosie cage is as dry as it should be you should never have crickets breeding in there. The
Grammastola rosea comes from the northern, slightly more hospitable, reaches of the atacama desert in chile. They don't need a moist environment. Most hydration will come from their food. If you want you can keep a full water dish in the cage so she can drink when she wants. You can also not have a water dish, and just offer one overnight every now, and then, or mist the side of the cage
lightly once or twice a week to somewhat reproduce dew that they may, or may not, drink in the wild. The substrate should be dry though at nearly all times, and never really needs to be damp.......... Hope some of this helps you a bit. Cheers,
Scott
