Cicadidae, commonly known as cicadas, are a family of insects known for their distinctive sound produced by males during mating calls. They are characterized by large, prominent eyes, broad heads, and transparent wings. Cicadas are found in various habitats around the world, particularly in warm climates, and are known for their life cycles, which can range from a few years to over a decade. Cicadas undergo a unique life cycle that includes several stages: egg, nymph, and adult. The nymphs live underground for most of their lives, feeding on plant roots before emerging as adults. Their loud calls, often associated with summer, are produced by specialized structures called tymbals. Cicadas play a role in ecosystems as pollinators and as a food source for various predators.
