Fortunately, cicadas are not harmful to humans. Usually, the noise they make can be a boon.
“Hopefully, any annoyance at the excitement is simply offset by how often – and amazingly – this event is.”
However, they are a danger to orchids, vines and trees because of its female egg laying habits.
“Cicadas can occur in large numbers and growers in predicted areas of activity should be cautious,” said Doug Pfeiffer, a professor and extension specialist at Virginia Tech’s Department of Entomology.
The cicadas are large, cleared of insects with insects that occur either yearly or seasonally. It is a mystery why seasonal cicadas only appear every 13 or 17 years, but are prohibited from avoiding syncing of predator cycles.
