Locusts and cicadas are two types of insects that are often confused with one another due to their similar appearance and behaviors. However, they belong to different families and have distinct characteristics. One of the main differences between locusts and cicadas is their seasonal appearance. In this article, we will delve into the world of locusts and cicadas, exploring their life cycles, habits, and the times of the year when they are most likely to appear.
Locusts: Seasonal Appearance and Life Cycle
Locusts are a type of grasshopper that is known for their ability to form large swarms and cause significant damage to crops and vegetation. The desert locust, for example, is a species that is found in Africa, Asia, and the Middle East, and is considered to be one of the most destructive locust species in the world. Locusts typically appear in the spring and summer months, when the weather is warm and humid. During this time, they undergo a process called “gregarization,” in which they change color, behavior, and physiology, and begin to form large swarms.
Locust Life Cycle
The life cycle of a locust consists of three stages: egg, nymph, and adult. The female locust lays her eggs in the soil, which hatch into nymphs after a period of several weeks. The nymphs then go through a series of molts, shedding their skin as they grow and develop. After several weeks or months, the nymphs reach adulthood, at which point they are capable of reproducing and forming swarms.
| Locust Stage | Duration |
|---|---|
| Egg | 2-4 weeks |
| Nymph | 6-8 weeks |
| Adult | 2-6 months |
Cicadas: Seasonal Appearance and Life Cycle
Cicadas, on the other hand, are a type of insect that is known for their distinctive songs and long life cycles. There are several species of cicadas, but the most well-known is the periodical cicada, which appears in large numbers every 13 or 17 years. Cicadas typically appear in the spring and summer months, when the weather is warm and humid. During this time, they emerge from the ground, where they have been living as nymphs, and begin to molt and transform into adults.
Cicada Life Cycle
The life cycle of a cicada consists of three stages: egg, nymph, and adult. The female cicada lays her eggs in the branches of trees, which hatch into nymphs after a period of several weeks. The nymphs then fall to the ground, where they burrow into the soil and begin to feed on the roots of plants. After several years, the nymphs reach adulthood, at which point they emerge from the ground and begin to reproduce.
| Cicada Stage | Duration |
|---|---|
| Egg | 6-8 weeks |
| Nymph | 2-5 years |
| Adult | 2-6 weeks |
Comparison of Locusts and Cicadas
Locusts and cicadas are both insects that appear in large numbers during the spring and summer months. However, they have several key differences. Locusts are known for their ability to form large swarms and cause significant damage to crops and vegetation, while cicadas are generally harmless to humans and are an important food source for many animals. Additionally, locusts have a much shorter life cycle than cicadas, with some species completing their life cycle in as little as 6-8 weeks.
