Trillions of cicadas to emerge across US 'in biggest invasion in centuries'

Trillions of cicadas are about to emerge in parts of the US in numbers not seen in decades and possibly centuries.

People in the southeast of the US are set for a "sight to behold", experts say, as periodical cicadas - which usually surface every 13 years - will emerge coinciding with another brood which come out in a 17-year cycle this spring.

While annual cicadas, which are bigger and greener than their black-bodied cousins, can be found anywhere in the world, periodical bugs, which are black in colour and have red, bulging eyes, can only be found in North America.

The dual emergence of the periodical cicadas, who are infamous for how loud they can be, is a rare phenomenon and is estimated to have last happened 221 years ago in 1803, when Thomas Jefferson, one of America's founding fathers, was US president.

University of Connecticut cicada expert John Cooley called the upcoming duel invasion "cicada-geddon".

At times mistaken for locusts, the bugs' buzzing can reach a volume of 110 decibels.

"Periodic cicadas don't do subtle," Mr Cooley said.
