With predators being high on the food chain and always on the lookout for a meal, prey must constantly avoid being eaten. Adaptations that prey employ adds to the chances of survival for the species. This work takes a fresh, modern approach to investigate and explain the predator and prey relationships of insects and spiders, the major terrestrial fauna on earth. Devoted to broad and in-depth analysis of arthropod defenses against predators, the book's approach is both experimentally and theoretically based with major emphasis on evolution, predator strategies and tactics, and prey /5(2).

The review article describes the ethological defence mechanisms in insects. This group of animals live in all climatic zones and have conquered all the habitats therein. In order not to become prey, insects employ various defence mechanisms - passive and active - or both these forms simultaneously or in a definite order. Because of their great variety, we have focused on passive defence only Cited by: 3. Small insects make a tasty meal for many other animals. Different species have developed their own special ways of protecting themselves. Some, like the red underwing moth in this picture, are masters of disguise, hiding from predators by blending in with their surroundings. Other insects use bright colours to scare off predators.

This chapter describes the major types of defensive behaviors of insects and to illustrate how, when, and why these defenses are of survival benefit. Survival and reproduction are the key elements of life. For both elements, defense is a paramount feature; without . Defence Mechanisms. Displaying all worksheets related to - Defence Mechanisms.
