Is this the true origin of the word antechamber?

Matt already wrote about wasps.  But I can't get enough of a clade that made Charles Darwin question the existence of God, writing:

I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars

How would Darwin feel about about a wasp that not only practices mass provisioning, dragging spiders into a hollow canes then sealing them into individual chambers to be eaten by its larvae, it then caps the end of the whole structure with ant corpses?  Maybe to keep other preditors away.  Maybe just to bring the room together?

Still, I can't decide if this is the most bizarre thing about wasps.  Polydnaviruses, mutualistic viruses injected with wasps eggs that disarm the parasitized host's immune system are right up there.  Or sex determination in wasps could make up an entire post.  Not only are there a variety of different mechanisms for determining sex like parthenogenesis, with some mechanisms completely dependent upon Wolbachia bacteria, some parasitic wasps manipulate sex ratios to suit the size of their host, laying smaller male broods on smaller hosts.  Nasty, awesome, or both?
