Hey, the cotesia glomerata; featured here, does alter the caterpillars mind in much the same way as the hook worm (snail parasites) it just does it in a different way. both are undoubtbly amazing, but for a catterpillar to stop growing, stop eating, stop functioning on its own; 'mind control' is apparent.

As the larvae exit the lepidoptera (caterpillar) one or two stay behind and in a way sacrifice themselves for their siblings, this one or two invaders we speculate may be the reason for the caterpillars altered behaviour. They stay to keep secreting the sunbstance needed to sustain the caterpillars change. Much like the hookworm must stay in the ants brain to control it.

In no other animal is so much evolutionary power visible.

I wonder, if they sponteanously gained self preservation instincts like that of our own; Would they still be able to thrive?
