Did you see the botfly pic I edited to my first post? If you're squirmy about gore and stuff, you should probably spare yourself from the sight.
EDIT: Hey I was thinking, since humans get their lives drastically extended when they drink Predator blood, would a botfly's or even a mosquito's life be drastically extended as well? What about the Predalien's? Btw, does the botfly's reproductive cycle remind anyone of the Alien's?
