There are more details here at wiki
http://en.wikipedia.org/wiki/Cheese_fly

These fly's are able to live inside your intestines and stomach and come and feast and lite on dead bodies...after some time.. I think the cheese fly's are magots.. and they can even jump as larve...ooohYUCK!

You can find them in rotting meats etc dead decaying rotting bodies etc!. It is also put onto cheeses  "In Sardinia, Italy the larvae are intentionally introduced into pecorino cheese to produce casu marzu." (from wiki)

Can actually make you sick if eaten!

"If eaten (accidentally or otherwise), the larvae can pass through the digestive system alive (human stomach acids do not usually kill them) and live for some time in the intestines. This is referred to as an enteric myiasis. Cheese fly larvae are a leading cause of myiasis in humans, and are the insect most frequently found in the human intestine.[1] The larvae can cause serious intestinal lesions as they attempt to bore through the intestinal walls. Symptoms include nausea, vomiting, pain in the abdomen, and bloody diarrhea. Living and dead larvae may pass in the stool.

Forensic entomology uses the presence of Piophila casei larvae to help estimate the date of death for human remains. They do not take up residence in a corpse until three to six months after death.[2]" (from Wiki)
