Just so you know,the "good humidity" bit goes against what they like. I keep our slings bone dry,with a few drops of water every couple weeks.Juvies/adults will need dry substrate with a water dish,which more that likely will get webbed over.
Not entirely correct. The explanations given by other members are one of the causes - it probably hasn't settled in yet because it just moved in recently or the setup isn't suitable. If a species is known to web a lot, it will web a lot even if there are individual behavioral differences. From my experience, if a T known to web a lot doesn't web at all, it is either very old or sick.
+1 to this. I have several fake plants in both my gbb and obt enclosures and they web like crazy
This is going to be a tough one to solve. You're asking us to delve into the mind of a creature that is so alien to us that some insist it has no "mind" at all, living solely by instinct.
What would you think would be a "good humidity?"
Why leaves? What are you trying to accomplish here?
Given that it's very difficult to MAKE any tarantula do anything (it's a lot like trying to herd a cat!), my guess is that there's something about it's caging and your care that is either making it so uncomfortable that it isn't interested in setting up housekeeping in that cage at all; is so comfortable that it instinctively doesn't waste the energy and silk to produce a web; or is an immature male that is "feeling his oats" well in advance and simply not interested in settling down in anticipation of his ultimate molt.
My original post did suggest that if the substrate wasn't suitable it wouldn't web, because it could just never settle in. But if everything is fine and it doesn't web, either it is old or sick.
One thing that we can make any T to do with a better chance of success - threat displays.
