The cicadas are back.

[Catherine]

The cicadas will soon emerge from the ground after 17 years. All this time they have been in the nymph state. 
There will be millions of them, but they are harmless. They are just a little noisy.  
It is a very long cycle for an insect. There are lots of theories as to why.

It is a strange life they have. Most of it is spent underground as a nymph. Their time as adults is very short. They emerge so they can mate and lay eggs that will become nymphs that will lie dormant underground for another 17 years.

Lots of people don't like the sound of cicadas, but their loud buzzing is funny and interesting.

This time they emerge in a very different world.
