Song of the cicada

Don’t worry, there is nothing wrong with your hearing. That sound you hear when your step outside — a sort of droning, whirring, buzzing, chirping kind of deal — is the song of the cicada. According to Mr. Wiki, these are the periodic cicadas which spend most of their lives as underground nymphs, emerging only after 13 or 17 years, which may reduce losses by starving their predators and eventually emerging in huge numbers that overwhelm and satiate any remaining predators.
