Actually, we talk of mimicry when a species mimics or imitates another species, like, for instance, the Milk snake (Lampropeltis triangulum – Lacépède, 1778) that imitates the Common coral snake (Micrurus fulvius – Linnaeus, 1766) whilst we talk of cryptism when one species imitates the substratum on which it lives, like for instance our leaf insect that is able to imitate and literally merge with the leaf hosting it, like the branches for the stick insect. Both mimicry and cryptism are strategies against predators.
