This summer, millions of cicadas are set to emerge from the ground, marking a significant event in their reproductive cycle. In a year already filled with unusual happenings, these flying insects will make their appearance, bringing with them a chorus of loud, incessant calls.
Cicadas have a fascinating life cycle, emerging every 13 or 17 years, depending on their species. This year, particularly in areas such as southwestern Virginia, parts of North Carolina, and West Virginia, populations could reach as high as 1.5 million cicadas per acre. The loud mating calls of male cicadas will certainly make their presence known.
Experts from Virginia Tech and Virginia State University have noted that cicada activity typically begins in May, peaks in early June, and most will be gone by July. Fortunately, these insects are harmless; they lack stingers and are not poisonous, so there’s no need for concern if you encounter them.
As the mature nymphs emerge after spending years underground, they construct mud turrets known as cicada huts before climbing onto vertical surfaces like trees or plants. They then shed their exoskeletons, leaving behind remnants that can often be seen on tree trunks. The emergence of cicadas is a synchronized event, with most of them appearing within just a few nights.
“Communities experiencing a massive influx of cicadas might face considerable noise,” says Sarah Mitchell, an entomologist at Virginia Tech’s Department of Entomology. “However, the rarity and wonder of this phenomenon often outweigh the temporary disturbance.” This year, the brood IX cicadas will reappear, having last emerged in 2003.
The 13- or 17-year emergence cycle is believed to be an evolutionary strategy to evade predators, as these prime number intervals reduce the likelihood of synchronizing with their cycles. “These insects are truly intriguing,” remarks Jake Thompson, a professor in the Department of Entomology at Virginia Tech. “If you don’t have fruit trees or grapevines to safeguard, take the time to appreciate this unique spectacle while it lasts.”
