Snake
The snake is likely the biggest and scariest predator of butterflies. The Serpentes suborder includes the long, limbless, carnivorous snake. Because of its size, the butterfly frequently cannot defend itself against a lesser snake that can eat it whole. The fact that snakes become passive during the digestion process is an unusual trait. Because digestion is an energy-intensive process, it is possible for the serpent to regurgitate its just digested butterfly if there is a disruption.
Snakes can be the predators of almost anything! The Adder, for example, when fully grown can gobble up large species of animals, like frogs, mice, lizards, slow worms, and so on. Young Adders, however, feed on beetles, spiders, worms, and grass-feeding caterpillars. Although these species of snake look dangerous, they rarely attack humans, unless of course, you step on it or pick it up.
