Cicadas awake four years early for unknown reasons

Uhhh, they have two major cycles... like a 13 and 17 year or something like that.
And you hear some every year.

Yes, we get them every year here in Texas.

They go in cycles within the 7 year cycle.

The cycles themselves refer to swarming of them every 7 years.

There are cicadas all the time in their season, in other words.

Their large swarm cycle happens about every 7 years.

I'm in Florida. It's 11:20 am and I hear a few outside right now.

I hear them most days all the time.

You'll know it's the peak of their cycle when there are thousands of them sitting on everything and the sound is maddening.

A quick Google search can make the world around you less confusing.

It's the Alexandria library in the palm of your hand.

They ran a special on it in st Louis on the CBS outlet. The scientist said it's every 17 years that the big swarm comes here, and they are four years early. Other than that, I know nothing about them.
