Flies?
It's hard to imagine more versatile, ecologically important and downright annoying animals than houseflies and fruit flies. They are nature's ultimate recyclers, feeding on and converting almost anything into a tasty and highly nutritious biofuel.
Their eggs, maggots, pupae and/or adults are preferred foods for a wide range of animals from spiders, mantids, fish, frogs, lizards. shrews, mice, birds and many others.
