Bisan

The bisan is a jungle dryad, specifically the dryad of camphor trees. But this chick's more dangerous than your run of the mill dryad. While other tree nymphs with wrap you up with roots, charm you into pretty please don't cut down my tree, and then stab you some, the bisan will wake up the trees around her to beat you up. Then she'll turn into a wasp and sting the holy bazoozoos out of you. That's what you get.

The bisan, like the bajang, is a Malaysian spirit. Walter William Skeat talks about it briefly in Malay Magic (I should really buy that book), where you get like maybe two pages of info. Plenty of elbow room for Wizards to transform a cicada spirit that's maybe female into a sexy lady who is also a wasp. Honestly, if I lived in a jungle where you got super loud cicadas with wingspans of up to 20cm I would totally say that's a spirit and make it some offerings so it doesn't attack me.
