Rare double brood of cicadas emerging in the coming weeks

(CNN)– Another rare event is coming but I don’t think we’ll be as excited for this one.

The Cicadas are emerging soon and there could be more of them than the world has seen in 200 years.

According to experts, some trillion cicadas will start appearing in May and live for about 6 weeks as part of a dual emergence.

For the first time since 1803, two specific groups of Cicadas will appear at the same time.

After they emerge and molt the males will start buzzing to find a mate and the noise can be louder than a plane.

The cicadas will eventually die off and it will be another 221 years before the two groups appear together again.
