Cicadas, those fascinating and often noisy creatures, captivate our attention with their unique life cycle and behavior. However, have you ever wondered how long these intriguing insects actually live? In this article, we will explore the lifespan of cicadas and answer some common questions related to their existence.

What is the average lifespan of a cicada?

Cicadas have one of the most prolonged lifespans among insects. On average, their lifespan can range from two to six years, depending on the species.

Why do cicadas live underground for most of their lives?

Cicadas spend most of their lives as nymphs, which are juveniles that undergo several stages of growth underground. They do this to protect themselves from predators and to find nourishment from the roots of trees or other plant sources.

When do cicadas emerge from underground?

After spending several years in the soil, cicadas emerge from underground when the temperature reaches a consistent 64 degrees Fahrenheit. This typically occurs in the late spring or early summer.

What happens during the emergence of cicadas?

When emerging from underground, cicadas undergo a remarkable transformation. Their exoskeleton splits open, and the adult cicada emerges, leaving the empty shell, or exuvia, behind. The newly emerged cicada then takes some time to harden its exoskeleton before it is fully prepared for flight.

How long do adult cicadas live?

After the emergence, adult cicadas live for a relatively short period, usually about two to four weeks. During this time, they mate and lay eggs for the next generation.

Why are cicadas so noisy?

The loud noise associated with cicadas is primarily produced by male cicadas. They have specialized organs called “tymbals” on their abdomen, enabling them to produce the signature sound by vibrating these organs rapidly. The purpose of this noise is to attract female cicadas for reproduction.

Do all cicadas have the same lifespan?

No, not all cicadas have the same lifespan. There are two main groups of cicadas: annual cicadas and periodical cicadas. Annual cicadas emerge every year, while periodical cicadas appear only once every 13 or 17 years, depending on the species. The periodical cicadas have the longest lifespan within the cicada family.

Why do periodical cicadas have such long lifespans?

The extended lifespan of periodical cicadas is linked to their unique reproductive strategy. By emerging in large numbers and synchronized cycles, they reduce the chance of being eaten by predators. Their large numbers also increase the likelihood of finding a mate, ensuring the survival of their species.

In conclusion, cicadas are fascinating insects with a relatively long lifespan compared to many other insects. From spending years underground as nymphs to their short-lived but noisy adult stage, cicadas continue to captivate scientists and nature enthusiasts alike. Whether they emerge annually or periodically, these resilient creatures hold a vital place in nature’s intricate web of life.
