Bumblebee Jasper isn't a bug, nor is it jasper, but I suppose it has some similar coloration. The stone is mined in Indonesia from volcanic vents where the alchemy is reported to be coal being turned into sulphur. I've been told that geologic forces flooded the main source and can no longer be mined. Then again, the same vendor was trying to sell me some (rare) Bumblebee Jasper.

I have a slab and have made a couple cabs with the stuff. It's very soft to work with, especially the desirable yellow material. I'm also told it contains arsenic and other vulcan nasties, so it's pretty... but beware!
