It amazes me. How does that wasp know exactly where and when the egg must be laid? For it must be laid inside the cell of the alien larvae - sometimes laid directly on the body of the prey, sometimes inside the host larva, where it will develop and eat the host from the inside out!

The great Charles Darwin came up against one of the greatest tests of his religious faith when studying the Ichneumonidae and contemplating their seemingly evil and cruel ploy for exploiting other creatures; he thought the monstrosity too evil for God to have thought of it, much less condone it.

He wrote, in 1860, "I own that I cannot see as plainly as others do, and as I should wish to do, evidence of design and beneficence on all sides of us. There seems to me too much misery in the world. 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, or that a cat should play with mice."

This wasp was indeed busy - I saw her lay a dozen eggs in several different flowers in about 15 minutes
