Grasshoppers are a group of mostly herbivorous insects in the suborder Caelifera within the order Orthoptera.

Grasshoppers are a group of mostly herbivorous insects in the suborder Caelifera within the order Orthoptera. They are known for powerful hind legs used for jumping, chewing mouthparts, and a life cycle that includes incomplete metamorphosis. In Canada, about 140 species are reported, especially common in western grasslands.

Classification and name

In the strict zoological sense, grasshoppers are members of the suborder Caelifera within Orthoptera. Some sources use the term more broadly, but encyclopedia treatment commonly centers on Caelifera as the main grasshopper group.

Physical characteristics

Grasshoppers have a three-part insect body consisting of head, thorax, and abdomen. They possess chewing mouthparts and strong hind legs that allow them to leap. Their front legs are shorter and used for grasping food.

Life cycle and behaviour

Grasshoppers are hemimetabolous, meaning they do not pass through a complete metamorphosis. They hatch as nymphs and gradually resemble adults after several moults, developing from egg to nymph to adult.

Ecology and economic importance

Grasshoppers are an important part of food webs and are eaten by predators such as birds, frogs, and snakes. A small number of species can damage crops and pasture, especially during outbreaks when some species swarm as locusts.
