Insects can also be useful in less grizzly cases - for example, they can help identify the source of illegal drugs. The environment in which a dead body is placed also affects its rate of decay. Ambient conditions affect both how soon after death the blowflies arrive and how quickly the maggots develop. Whats different is how quickly the decomposition process takes place.
