How does camouflage protect animals?

Insects try to protect themselves from their enemies by using the following forms of camouflage:

An insect protects itself by conforming to the general image of its environment.

The green stink bug is green in the summer half-year and falls on leaves
only a little on. In autumn, just before wintering, it turns brown,
to turn green again in spring.

The C-butterfly hibernates between dead leaves
due to the jagged shape and the brown-gray color of the
Very well camouflaged undersides of the wings.

An insect protects itself against optically oriented enemies by the physical correspondence of its external shape and color with an animate or inanimate part of its environment.

The young swallowtail caterpillar protects itself by keeping in shape
and color resembles bird droppings.

The dead leaf perfectly mimics a dried up leaf

A harmless insect protects itself by having a stronghold, e.g. B. protected by a poison sting from many predators, imitates insect.

The hornet-glass-winged butterfly, a harmless butterfly, protects itself by imitating the defensive and poisonous hornet.

Hornet glass winged: completely defenseless

Hornet: armed with poison sting and strong pines
However, mimicry is only effective if the original and the imitator are in the same biotope during the same period.
