Apparently, the sun is going to have a huge solar flare that releases an EMP, that will knock out all electronics.
And that will happen today, February 22nd, 2013.
This is the Tarantula Hawk Wasp...
It is a wasp that hunts down the massive spider in the desert in order to paralyze it with it's sting, then take the limp body back to it's layer in order for hit's you hatchling to eat once it breaks free from it's shell. Amazingly big and I hear the sting from one of these is pretty intense.
This seems to be the most fun extreme of it's size but they usually range from 2-4 inches in length
