This summer, expect a significant emergence of cicadas as millions of these distinctive insects make their way to the surface for their mating ritual. The year 2020, marked by various global events, also brings with it the return of cicadas, known for their loud and unceasing calls.
Understanding Cicada Life Cycles
Cicadas emerge from the ground every 13 or 17 years, depending on the species. This year, regions in southwestern Virginia, North Carolina, and West Virginia will witness the spectacle, with up to 1.5 million cicadas per acre expected to surface. The male cicadas produce a characteristic mating call, making their presence unmistakable.
Research from Virginia Tech and Virginia State University indicates that cicada activity typically begins in May, peaks in early June, and tapers off by July. Those concerned about encountering these insects need not worry; cicadas are non-toxic and lack stingers.
The Remarkable Life Cycle of Cicadas
The life cycle of cicadas is quite remarkable. After 13 or 17 years underground, mature nymphs build a mud structure, referred to as a cicada hut, and climb to the surface. They then molt into their adult form, leaving behind their exoskeletons attached to nearby trees. This emergence tends to be synchronized, with many adults appearing within a few nights. Male cicadas produce their distinctive sounds by vibrating membranes located on their first abdominal segment, while females remain silent.
Community Impact and Insights
According to entomologist Sara Thompson from Virginia Cooperative Extension, communities experiencing this mass emergence may face considerable noise challenges. However, she emphasizes that the rarity and wonder of this phenomenon can help mitigate any annoyance. This year’s emergence features the brood IX cicada, which last appeared in 2003. The evolutionary reasoning behind their long emergence cycles is thought to be a strategy to avoid synchronization with predator populations.
Appreciating Nature’s Wonders
