What's to Blame for This Year's Cicadas Invasion?

The season of cicadas is now fully upon us as the exasperating insects emerge from the ground in record swarms. For weeks, Americans were warned that the bothersome bugs would be popping up in historic numbers. One woman was enjoying some time outdoors when she became the unwitting victim of a cicada "fly-by." Once they emerge, cicadas have a lifespan of about four weeks. The current invasion should die off in July.
