cicada

Cicadas are fascinating insects famous for the incredibly loud buzzing sound they make during the hot summer months. These creatures spend most of their lives underground as nymphs, feeding on sap from plant roots. Then, after years—sometimes more than a decade!—they emerge en masse, shed their skins, and transform into winged adults whose main job is to mate and lay eggs before their short adult lives end. Think of it like a secret underground society suddenly bursting onto the scene for one glorious (and noisy!) summer.

The sound cicadas make isn't a chirp or a song; it's actually produced by vibrating a special organ called a tymbal. Different species create different sounds, and the chorus can be deafening! Some cultures even consider the emergence of cicadas to be a sign of good luck or a symbol of rebirth. You might read about them in stories set during long, hot summers, evoking a sense of nostalgia and the passage of time.

Cicadas are insects belonging to the order Hemiptera, known for their prominent eyes, sturdy bodies, and—most famously—their incredibly loud, high-pitched calls. These sounds aren't made with vocal cords like birds; instead, male cicadas vibrate a specialized organ called a tymbal (a ribbed membrane on their abdomen) to create the buzzing or clicking noise that attracts mates.

What makes cicadas truly unique is their life cycle. Many species spend several years—often 2–5—living underground as nymphs, feeding on xylem sap from plant roots. These nymphs molt several times before climbing up trees or other surfaces, splitting their old skins, and stepping out as winged adults. In North America, a few “periodical” species do this on 13- or 17-year schedules, emerging in massive, synchronized numbers (sometimes millions!). That kind of synchronized appearance is what people usually mean by a periodical cicada emergence, and it can be truly spectacular.

The adult cicadas often live only a few weeks, dedicating their energy to mating and laying eggs. After laying their eggs in tree branches, the adults die off, and the cycle begins anew with the next generation of nymphs burrowing underground.

Cicadas have been featured in art, literature, and folklore for centuries. In some cultures, they symbolize immortality or rebirth due to their long life cycles and dramatic emergence. They're often used as a metaphor for hidden potential or the cyclical nature of time. You might encounter them in poetry describing summer landscapes, or in stories about rural life where their buzzing is an integral part of the soundscape. For example, in Homer's Iliad, cicadas appear in a vivid summertime comparison. So next time you hear that distinctive buzz on a warm day, remember the incredible journey of the cicada—a creature deeply connected to the earth and the rhythm of the seasons.
