Millions of cicadas will emerge after 17 years underground in the United States.

As if the context of being in a pandemic were not enough, added to the giant killer hornets that invade the United States shortly, millions of cicadas will emerge from the ground after being 17 years underground.

Every 17 years, millions of cicadas that live underground living on the sap they suck from the roots of trees emerge into the light. From June to August this year they will invade the US They live for a few months and cause a deafening noise.

On average, up to 1.5 million cicadas can emerge per acre (0.4 hectares), and this year people living in southwestern Virginia, parts of North Carolina and West Virginia could witness this unique phenomenon that causes a strange noise similar to "thousands of out of tune car radios

Communities and farms with large numbers of cicadas emerging at once may have a substantial noise problem"Said Eric Day, Virginia Cooperative Extension entomologist in the Virginia Tech Department of Entomology.

Fortunately, any annoyance from the disturbance is tempered by how rare and surprising this event is.”.

However, they are a danger to orchids, vines, and trees due to the spawning habits of female cicadas.

Cicadas can occur in overwhelming numbers and growers in anticipated activity areas need to be vigilant"Said Doug Pfeiffer, professor and extension specialist in the Department of Entomology at Virginia Tech.

Cicadas are large, open-winged insects that appear annually or periodically. It is a mystery why cicadas only emerge every 13 to 17 years, but there is a theory that it is to avoid synchronizing with predator cycles.

Cicadas pose no danger to humans. Despite their large size, they do not bite and are largely harmless, even to pets.

After a few months of flying, mating and filling the forest with their deafening songs, the adult cicadas die at the end of the summer.
