Insects are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae.
Grasshopper (Caelifera)
The grasshopper can leap 20 times the length of his body. There are more than 20,000 species of grasshoppers. They have no ears, but they do hear with an organ called tympanum. When grasshoppers are picked up, they spit a brown liquid that protects them from attacks by predators. Males sing, by rubbing their back legs against their wings, to attract females and to warn off other males. Grasshoppers are herbivores, they will eat almost any type of leaves, but they prefer soft vegetation.
Ant (Formicidae)
Ants are capable of carrying objects 50 times their body weight. The total population of ants in the world is roughly equal to the population of people in the world. Ants were living back with the dinosaurs. Army ants may prey on much larger animals such as reptiles, birds, or even small mammals.
