Long time, if ever I think. Pretty sure it's very difficult to legally obtain wildlife from Sri Lanka if not impossible- they were ahead of India on this front if I am not mistaken. Some will probably be poached here and there but not easy to get those on to the market these days due to the known regulations... fruit of the poisoned tree kind of thing. I certainly hope they are being protected and of course it would be very fun to have a new Pokie in the hobby. But I'd rather them stay in situ as long as they are protected. Captive conservation is nice too, we would all like to see examples of every tarantula species being raised in captivity. But the spirit of captive conservation does not condone poaching at all nor over-collecting from the wild as that is counter to the purpose of conserving period. A neat thing to learn of though, thanks for posting!
