Mimesis refers to the ecological adaptation phenomenon in which one organism simulates another organism in terms of morphology, behavior, etc., so that one or both parties can benefit. It is a special behavior formed by animals in the long-term evolution of nature. Mimicry includes three parties: the imitator, the imitated, and the deceived.
For example, the inchworm is very similar to a branch, and the larvae of the butterfly are very similar to guano.
One, the dead leaf butterfly.
The dead leaf butterfly is a large butterfly that is known for its wings and markings that resemble dead leaves in the front and hindwings.
The back of the wing shines with a dark blue, purple blue or light blue luster, which varies according to the season.
Adults are extremely good at flying, flying high and agile, with wings that can withstand rain and moisture in dense forests.
When the dead-leaved butterfly is hunted by birds and is in danger, it will fly in an irregular, deranged manner, quickly falling between the leaves of the plant, and then quickly fold its wings and stand still. Butterflies at this time reveal the pattern on the outside of their wings, resembling a sun-dried dead leaf, and birds are usually unable to spot them in a fully mimetic camouflage.
Other mimetic masters who can disguise themselves as leaves.

(Malayan leaf frog, endemic to the tropical rainforests of the Malay Peninsula, Sumatra and Borneo Islands.) ）
Second, plant mimicry.
Not only do animals on Earth have mimetics, but plants also have a large number of mimics.
For example, the petals of some orchids mimic the appearance of some female bees in terms of shape, color and hairiness, which can attract male bees to "cross their tails" with them, and obtain results that are conducive to pollination.
a, bee orchid.

(Males love bee orchids more than females.) ）
b, Nepenthes.
Nepenthes carnivorous plant; it has a unique nutrient-sucking organ, the pitcher is cylindrical, the lower half is slightly expanded, and the cage has a lid on the mouth, so named because of its shape like a pig cage.
(N. nepenthes predation.) ）
c, Cobra bottle grass.
Cobra grass is a very well-known species of carnivorous plant, named for its resemblance to glasses, and its ferocious shape makes other animals afraid to approach.
d, in the desert of southern Africa, there is also a strange camouflage plant, it shrinks its stem into a hemispherical shape, the surface is also covered with turtle carapace-like patterns, looking very much like a turtle shell, so people call it "turtle shell grass".
In times of drought, all its branches and leaves die, and only the short hemispherical stems are alive, like a turtle lying on the ground, so that it can deceive the eyes of plant-eating animals and survive. When the rainy season comes, branches and leaves quickly grow on the top of its stem, flowering and bearing fruit. The common tortoiseshell is of the same genus.
e, raw stone flower, also known as stone jade, the general name of the species of stone flower. Native to southern and southwestern Africa, it is commonly found in crevices and gravel in rock beds, and is known as a "living stone". In the non-rainy season, it grows and blossoms, and when it is in full bloom, the raw stone flowers are like covering the desert with a huge flower carpet. But when the dry summer came, the desert returned to the world of "stones".
