I sometimes talk to people who think nature is generally benevolent or cooperative. This system of reproduction seems to raise grave objections to that viewpoint.

Emerald cockroach wasp
The emerald cockroach wasp or jewel wasp (Ampulex compressa) is a solitary wasp of the family Ampulicidae. It is known for its unusual reproductive behavior, which involves stinging a cockroach and using it as a host for its larvae. It thus belongs to the entomophagous parasites.
I remember that when we were in Monte Verde in the Quaker reserve, a guide showed us figs that are a home for a wasp that lays eggs in it and the larvae feed on the fruit. The dry fig almost always has some insects in it, albeit dead.
What an interesting video! Thanks for sharing.
I wonder if this changes any exterminators minds on who is the tougher pest to handle?
