What’s the difference between locusts and cicadas? These two insects might seem similar at first glance, but they belong to different families and have distinct characteristics. Both are known for their loud, distinctive songs, but their life cycles, appearance, and behavior differ significantly. In this article, we will explore the key differences between locusts and cicadas to help you understand these fascinating creatures better.
Firstly, let’s talk about their classification. Locusts belong to the family Acrididae, which is part of the order Orthoptera. On the other hand, cicadas are part of the family Cicadidae, also within the order Orthoptera. This distinction is important because it highlights their different evolutionary paths and adaptations.
One of the most noticeable differences between locusts and cicadas is their appearance. Locusts are typically brown or green, with long, slender bodies and long antennae. They have a more robust and muscular build compared to cicadas, which usually have a more slender and elongated body shape. Cicadas come in a variety of colors, including green, brown, red, and even yellow, and they have shorter antennae than locusts.
Another significant difference lies in their life cycles. Locusts have a much shorter life cycle, with adults living for only a few weeks to a few months. During this time, they lay eggs in the soil, which hatch into nymphs. The nymphs then go through several instars (molt stages) before emerging as adults. In contrast, cicadas have a much longer life cycle, with some species living underground for up to 17 years before emerging as adults. This extended period allows them to feed on tree roots and grow to their full size before molting into their final adult form.
One of the most striking differences between locusts and cicadas is their behavior. Locusts are known for their ability to form swarms, which can cause significant damage to crops and vegetation. When conditions are right, locusts can multiply rapidly and form enormous swarms, which can travel long distances in search of food. In contrast, cicadas are generally solitary insects and do not form swarms. They are more concerned with finding a mate and reproducing than with causing widespread destruction.
Lastly, let’s discuss their songs. Both locusts and cicadas produce loud, distinctive songs, but the purpose and mechanism behind these songs differ. Locusts use their hind legs to rub against their wings, producing a high-pitched sound that can be heard from a great distance. This sound serves as a mating call and is also used to communicate with other locusts. Cicadas, on the other hand, use their tymbals, a specialized structure located on their abdomens, to produce their unique, high-pitched songs. These songs are primarily used to attract mates and are a crucial part of their reproductive process.
In conclusion, while locusts and cicadas might share some similarities, such as their classification within the order Orthoptera and their ability to produce loud songs, they are distinct insects with unique characteristics. Their different life cycles, appearance, behavior, and reproductive strategies make them fascinating subjects of study for entomologists and enthusiasts alike.
