Tarantula Hawk

http://en.wikipedia.org/wiki/Tarantula_hawk
When the wasp larva hatches, it rips a small hole in the spider’s abdomen, then plunges into the spider’s belly and feeds voraciously, avoiding vital organs for as long as possible to keep it fresh… Finally, the wasp becomes an adult, and tears open the spider’s belly to get out.
Tarantula wasps are also nectarivorous. The consumption of fermented fruit sometimes intoxicates them to the point that flight becomes difficult.
So the tarantula hawk is a bug that can kill a tarantula AND likes getting hammered? Badass.
That is, in theory. From afar. In practice… WHY THE FUCK WAS THIS IN MY BACKYARD AND NOW I AM TERRIFIED AND AM GOING TO HAVE NIGHT TERRORS FOR THE REST OF MY LIFE
