A cicada is a large "fly-like" insect with large membranous wings. The males make loud shrill sounds in tree-tops during the summer and early fall months. These sounds are used to attract female cicadas for mating. These sounds can sometimes exceed 100 decibels. Other common names for Cicadas are "Harvest Fly", "Locust" or "Heat Bug".
