Tarantula Hawk Vs. a Tarantula
The female wasp of this species finds these huge tarantula's and use a very intricate dance to sting their underside to paralyze them. Once paralyzed, the wasp drags the tarantula to a pre-dug hole and drags it inside. Once inside, the wasp lays a single egg on the tarantula. When the egg hatches, the young grub (wasp) dines on the paralyzed tarantula until grown. It then emerges from the hole to begin the grizzly cycle all over again.
These wasps reportedly have one of the most painful stings in the insect world - http://en.wikipedia.org/wiki/Schmidt_Sting_Pain_Index. Fortunately, they don't seem as aggressive as their yellow-jacket and paper-wasp cousins.
