They are real, and they're somewhere between creepy and fascinating. They aren't born zombies; it's chemically induced, --and is, perhaps, even a little more complex than the voodoo practice of using puffer fish powder to zombify human victims.
If you read my "T" post last week, I talked about fungal molds producing volatiles. This is an example of a fungus doing that, and it's seriously bad juju for the ant.
The ant is infected by a germinating spore of a parasitic fungus in the genus Ophiocordyceps. The spore sticks on the surface of the ant's exoskeleton and builds up pressure. When the pressure is sufficient, it explodes, blasting the genetic material inside the ant. As the infection grows, it produces a volatile (chemical) or several that affect the ant's brain. The ant then follows a new set of instructions, leaving its orderly colony and marching to a spot in the forest, up a tree, to the underside of a leaf facing north. It then sinks its mandibles into the vein of the leaf. And...then the ant dies.
The leaf is at a fairly specific elevation above the ground, and all of this happens before solar noon.
Scientists theorize that the fungus is guiding the ant to a place and time that controls the temperature and humidity.
The fungus consumes the ant, then pops a strange looking fruiting body out of the top of the ant. The fruiting body releases spores and voila! We start out all over again.
There are 150 species of ant controlling fungi, and each targets a single species of ant. And each has a little different modus operandi.
Nature is stranger than hollywood.
I hope this is some scifi writing inspiration. :-)
