Warning this is really gross.
Is there such a thing as a human bot fly? Yes, we're sorry to say there is. Called the torsalo, Dermatobia hominis, occurs in Mexico and Central America. Fortunately, getting one is an extremely unlikely occurrence for the average visitor.

2nd instar torsalo larva, note the hooks to hold it in place! One of the really cool things about this insect is that it lays its eggs on a mosquito and the eggs hatch when the mosquito feeds on a host. Do humans get warbles? Yes, (are you disgusted yet)?
While the maggot feeds on its host (you) it has to have a hole in the skin so it can continue to breath. It takes about 6 weeks to complete development on its host. There are stories of entomologists rearing torsalos on themselves in order to get a good specimen of an adult (which are rarely captured), but we regard this as taking your profession a little too far.
