Tom O'Dell says the return of the 17-year cicadas is an "unusual wildlife event" he hopes people can appreciate and not be too anxious about what will happen. He doesn't expect the cicadas to cause any significant damage and says they are no harm to humans as they don't bite or sting. He says he has seen a few around already but says the warm weather will cause that number to increase, and they will soon emerge in parts of southeastern Michigan and in a handful of other states in the eastern half of the country, after developing underground for 17 years.
