I'd totally prefer robotic insects. They don't bite you and spawn offspring in your flesh.
What, bees totally do that.
Bees don't but some spiders do. Imagine that after a holiday to the tropics you come home and there's a bulge on your leg. You try to remember making an appointment with the doctor just in case but you forget because you don't really notice the bump.
Until it starts itching really bad one night, you start scratching and scratching and then the bump starts to move and once you've panicked enough to break open your skin out come a hundred baby spiders, crawling down your leg in a rush for freedom.
