I started thinking after I posted about the PW's tasting funny but was too tired to make any sense of it.
When a body starts to decompose outside, flies are usually the first to come to the scene for a tasty meal and to lay their eggs, along with other various beetles and such. Once the maggots hatch, they begin the feeding frenzy and nothing will touch said body once maggots are present. It also makes me wonder if the maggots have evolved to have such a bad taste, so that nothing will eat them while they are cleaning up a decomposing body. I did an experiment one time when I was a kid to see if any predatory animals would come eat a baby rabbit that had been killed by a dog, once the maggots appeared, nothing would touch it. I know, I'm weird but it was in the name of science!
Hope this makes sense :shock:
