What are instincts and how do they manifest themselves in arthropods. Give examples

Instinct is the sum of innate tendencies and aspirations, which is expressed in the form of automatic behavior. In a narrower sense, it is a set of complex hereditarily acquired behavioral acts that are characteristic of individuals of a certain species under specific conditions.
In arthropods (especially insects) instincts have become quite complex in the course of evolution and have reached the heights of perfection. An example of a complex instinct is the building instincts of insects (bee honeycombs, anthills, cobwebs). Such an instinct as caring for offspring, consider the example of burrowing wasps. The wasp initially digs a burrow that leads to a cell where the paralyzed prey is piled up. An egg is laid in the body of the prey, from which the larva hatches. Then the weak larva has the opportunity to eat fresh food, which is paralyzed, therefore it does not deteriorate, but does not resist the parasite, which is saturated with its body.
In the type of arthropods, hereditary transformations of behavior have evolved by leaps and bounds. Insect instincts are adapted to all aspects of lifestyle. The life of an insect is within strict limits.
