Natures wonders: clever tiny wasp controls another (Introduction)

How this all works is not yet known, but a tiny wasp controls another to do its bidding:

"Crypt gall wasps (Bassettia pallida) lay their eggs in the branches of oak trees, where wasp larvae develop within compartments called crypts and the wasps eventually chew their way out as adults. But Scott Egan and Kelly Weinersmith of Rice University found that another wasp—a new species, much smaller than the crypt gall wasps and a beautiful iridescent blue—often occupy the crypts with the B. pallida larvae. Upon further investigation, the researchers learned that the small, blue wasp somehow commands the crypt gall wasp to dig a smaller–than-usual tunnel out of the oak branch. When the larger insect tries to escape, it gets stuck, plugging the hole with its head. The smaller wasp then eats the crypt gall wasp alive and ultimately exits through the hole.

"The researchers describe the new species, which they dubbed the crypt keeper wasp (Euderus set), in ZooKeys earlier this month (January 12), and published the details of their bizarre relationship with the crypt gall wasp in the Proceedings of the Royal Society B yesterday (January 24). While it remains unclear how E. set wasps manipulate their crypt mates, the study suggests that it is to their benefit: crypt keeper wasps that didn’t bunk with crypt gall wasps—and thus had to tunnel their own way out of the tree—were nearly three times more likely never to make it out alive.

“'This is the type of science I love; it leaves us hungrily asking more questions,” David Hughes from Pennsylvania State University, who studies manipulative parasites, told The Atlantic. For example, “how does this wasp get its egg into its soon-to-be excavator? And how does it do that so precisely to stop the activity at a stage where the hole is large enough just for a head to block, but not for the body of the manipulatee to emerge?'”

Comment: Wow! How did this get arranged. Not step by step. Looks like lots of pre-planning. We must eagerly await more research for explanations of the control mechanisms. Is this too minor for God to create?

The simplest explanation that can be for all of these wondrous things, is that everything is connected (therefore symbiotic by nature on a grand scale) - and therefore everything IS simply an ultimate Inventive Mechanism -Occam's Razor. Yes, could be that simple.
