A locust-type insect quite common in the southern United States. Some species do hibernate for seventeen years, but not all. They produce a very loud screeching sound somewhat similar to the sound of crickets but much more irritating. They typically are around all summer. They are terribly clumsy fliers; I've had several fly into my head.
The sound of the cicadas outside my window blocks out the sound of my TV.

Walking outside, the cicadas were deafening.

Cicada carcasses litter the Southern sidewalks come autumn.
