How do flies get to a recently passed body?

Question

How can flies get to a body that is in a coffin and sometimes surrounded in another concrete coffin?

Answer 1

the cant. maggots eat the body, and maggots are produced by the dead body. i guess its natures way of helpng decompose the body more quickly.

if there was a tiny opening in the coffin then maybe a fly could get in. or do the maggots turn into flies? i dont know about that one.
