The ones here can take a lot of sun if they have enough water and humidity. Those fuzzy phone lines are in full sun but in the rainy season the humidity stays over 80% most of the time and there are daily rains. So, in that condition, they can take the full blistering tropical sun. I doubt they even need watering if the humidity is high enough. I prefer to keep them in mostly light but not direct sun, maybe a few hours morning or evening. It's easier to keep them hydrated through the dry winter that way. When we were doing a lot of cave diving and thus hiking around in the outback, I would collect them in the jungle when they had fallen to the ground. The ones in the trees though were not in full sun but in filtered sun and light, they seemed to look healthier than any others. They are survivors, I think they are a lot hardier than it is assumed. They can't handle cold, and they don't like dry but outside of that they will manage.
