Wasps, roaches, brain surgury, and burrowing larva
This post that I saw over at boing-boing is a must-read.
The wasp slips her stinger through the roach's exoskeleton and directly into its brain… The zombie roach crawls where its master leads, which turns out to be the wasp's burrow… Now the wasp turns to the roach once more and lays an egg on its underside… The larva grows inside the roach, devouring the organs of its host, for about eight days. It is then ready to weave itself a cocoon--which it makes within the roach as well.
Whoa!
