Fables are crafted to convey the moral, rather than deriving the moral from natural circumstance.

I recall reading a tale with animals interacting with a human. There was something about the chicken wanting to be saved from the wolf, so it gave the human its eggs. The cow wanted to be saved from the wolf, so it gave the human its milk. The horse wanted to be saved from the wolf, so it gave the human its strength and speed. They all end up slaughtered and eaten by the human and his "dog" (a.k.a. the wolf) when they were no longer useful in any other way. The chicken stopped laying. snap The cow stopped milking. slice The horse went lame. bang The moral of the story was essentially, "hahahaha, you stupid animals got played!"

On a side note, any animal story where the dog does not side with the human is clearly bunkum. And in any animal U.N., clearly, the human is a veto-wielding permanent member of the security council, so the mosquito, the North Korea of unpopular animals, was just sucking up to a major power to get more food aid. And in that case, we should let the mosquito go pound sand, because they will never stop being annoying little jerks.
