From Wikipedia, some facts about the cicadas assaulting out ears in some portions of America:
Magicicada is the genus of the 13-year and 17-year periodical cicadas of eastern North America, consisting of seven species. Magicicada belongs to the cicada tribe Lamotialnini, a group of genera with representatives in Australia, Africa, and Asia, as well as the Americas.
Magicicada species spend around 99.5% of their long lives underground in an immature state called a nymph. While underground the nymphs feed on xylem fluids from the roots of deciduous forest trees in the eastern United States. In the spring of their 13th or 17th year mature cicada nymphs emerge between late April and early June at a given locality, synchronously and in tremendous numbers. The adults are active for only about 4 to 6 weeks after the unusually prolonged developmental phase.
The males aggregate in chorus centers and call there to attract mates. Mated females lay eggs in the stems of woody plants. Within two months of the original emergence, the life cycle is complete; the adult cicadas die and their brood disappears for another 13 or 17 years.
