What is the Difference Between Locusts and Cicadas?

🆚 Go to Comparative Table 🆚

Locusts and cicadas are different species of insects that belong to the same group of herbivorous winged insects. Here are some key differences between the two:

  • Family: Locusts belong to the same family as grasshoppers, while cicadas are related to crickets.
  • Appearance: Cicadas have large, clear wings and a rounded body, while locusts have a slim, straight body, big hind legs for leaping, and are generally smaller than cicadas.
  • Sound: Cicadas are known for their distinctive loud sound, while locusts produce a different sound.
  • Behavior: Locusts can swarm and cause significant damage to crops and plant life, while cicadas do not swarm and are less destructive when they feed.
  • Feedling Habits: Cicadas feed on plant sap, while locusts consume a variety of plant life.
  • Life Cycle: Cicadas have a longer life cycle, with some species emerging every 17 years, while locusts have a shorter life cycle.

Comparative Table: Locusts vs Cicadas

Here is a table comparing the differences between locusts and cicadas:

Feature Locusts Cicadas
Order Orthoptera (same as grasshoppers) Hemiptera
Family Acrididae (short-horned grasshoppers) Cicadidae
Appearance Slim, straight body; big hind legs for leaping Rounded body; big, clear wings
Size Up to 4 inches long Typically 2 inches long, half an inch across
Diet Plant-eaters, can destroy crops Primarily feed on plant sap
Sound Produce sound by rubbing their wings together Make a loud, shrill noise with their tymbals
Life Cycle Go through 5 stages: egg, nymph, wing-forming, and adult Go through 5 stages: egg, nymph, and adult
Destructiveness Can cause widespread crop damage and famine Generally less destructive to crops

Locusts are a type of grasshopper and are known for their large size, while cicadas have a more rounded appearance and resemble bees. Cicadas are typically about two inches long and feed primarily on plant sap, while locusts can reach up to four inches long and are known to destroy crops. Locusts travel in swarms and can cause widespread crop damage and famine, while cicadas are generally less destructive. Both insects can fly and produce loud noises, but they do so in different ways: locusts rub their wings together, while cicadas make a loud, shrill noise with their tymbals.
