Difference Between Locust and Grasshopper

Main Difference

The main difference between Locust and Grasshopper is that Locusts are grasshoppers which advance gregarious characteristics in the appropriate environmental conditions forming an established group whereas grasshoppers are ground lodging insects which go over a phase of incomplete metamorphosis before emerging into the adult stage.

Locust vs. Grasshopper

Locusts are grasshoppers which mature gregarious characteristics in the appropriate environmental conditions forming an established group whereas grasshoppers are ground lodging insects which go through a phase of incomplete metamorphosis before emerging into the adult stage. Locusts comprise the ability to occur in the solitary or gregarious phase, while grasshoppers can only exist in solitary.

A locust belongs to the family Acrididae, whereas grasshopper is an insect that fits the order Orthoptera. Locust is illustrating by a behavior known as swarming, whereas grasshopper is typically solitary and does not swarm. Locusts can source of plagues and large scale crop harm whereas grasshopper cannot do much harm on its level.

A locust is a form of a grasshopper which is shorthorn while the grasshopper is not a type of locust of the shorthorn. The locust contains only one family, whereas the grasshopper contains 28 distinct families. Locusts can occur in two different behavioral states which are migratory and gregarious while grasshoppers exist in only one state.

Locusts may revolutionize their body shape and color, fertility, and survival behavior, while grasshoppers generally cannot change their color or survival behavior. Locusts can form thick swarms and bands while grasshoppers generally do not. Locusts can travel over large distances while grasshoppers usually like to exist in one place.

What is Locust?

A locust fits a certain species of short-horn grasshoppers that are members of the family Acrididae and are describing by a behavior known as a swarming phase. Locust insects undergo behavioral and physiological variations upon reaching a high level of population concentration and differentiates a locust from a grasshopper.

Under suitable environmental conditions, they tend to breed and grow into swarms. Locust comprises one family. Locusts pose no harm until they grow rapidly and swarm. Locusts may revolution their body shape and color, fertility, and survival behavior. Locusts are not a major risk to agriculture as long as their numbers are low.

In drought under suitable conditions, something happens to these harmless insects as serotonin starts a series of changes in their brains. They breed exponentially and become gregarious and nomadic, forming huge swarms. The swarm of locust can travel great distances, causing damage to crops and clearing the green vegetation fields. Locusts can become a source of plagues and large scale crop damage.

What is Grasshopper?

Grasshoppers are a group of jumping insects belonging to the order Orthoptera, found in a variety of habitats. Experts consider that grasshoppers are the eldest prevailing group of plant-chewing insects. Grasshoppers are considered about around 250 million years old back to the Triassic period.

They escape from their predators by leaping into the air using their hind legs which are greatly enlarged and contain large muscles. Grasshoppers hatch from their eggs as nymphs or hoppers as they do not undergo a complete metamorphosis. They shed their skin several times as they mature into adults. Grasshoppers stridulate i.e the act of producing sound by rubbing a row of pegs on the hind legs against the forewings.

Male grasshoppers stridulate to attract sexually receptive females. Although in some species of grasshoppers female can also stridulate, the sound is not as loud as produced by the male species. Most species of grasshoppers are polyphagous feeders i.e., they eat vegetation from a variety of sources. Some species are omnivorous i.e., they eat animal tissues. Usually, they like to eat grasses, including cereal crops. Grasshopper cannot do much harm on its own.

Key Differences

  1. Locusts are grasshoppers which develop gregarious features in suitable environmental conditions forming an establish group whereas grasshoppers are ground lodging insects which go through a phase of incomplete metamorphosis before emerging into the adult stage.
  2. Locusts comprise the ability to exist in the solitary or gregarious phase; on the other hand, grasshoppers can only exist in solitary.
  3. A locust belongs to the family Acrididae on the flip side grasshopper is an insect that belongs to the order Orthoptera.
  4. Locust is describing by a behavior known as swarming on the contrary grasshopper is typically solitary and does not swarm.
  5. Locusts can cause plagues and large scale crop damage conversely grasshopper cannot do much harm on its own.
  6. A locust is a form of a grasshopper which comprises shorthorn; on the other hand, the grasshopper is not a type of a locust.
  7. The locust contains only one family, whereas the grasshopper contains 28 distinct families.
  8. Locusts can occur in two different behavioral states which are migratory and gregarious unlikely grasshoppers do not exist in two states.
  9. Locusts may alternate their body shape and color, fertility, and survival behavior oppositely grasshoppers generally do not comprise these features.
  10. Locusts can form dense swarms and bands on the flip side grasshoppers generally do not.
  11. Locusts can travel over large distances while grasshoppers cannot travel a long distance.

Conclusion

Above this discussion, it concludes that Locusts are grasshoppers which advance gregarious features in suitable environmental conditions forming an establish group whereas grasshoppers are ground lodging insects which go through a phase of incomplete metamorphosis before emerging into the adult stage.
