'Like magic': small emergence of cicadas thought to be extinct found in New York 06/12/2021 1:21 BOHEMIA, N.Y. (Reuters) - Dr. Elias Bonaros, a cardiologist and cicada expert, thought the noise-making insects - which emerge from the ground every 17 years - might not return to his neck of the woods, New York state's Long Island, after very few showed up in 2004. But this week they came back. Bonaros, 48, has always loved the bugs. "I was about 5 years old and my father one day caught a cicada in the summertime, put it in my hand, nature's natural noisemaker," he said in Connetquot River State Park Preserve on Long Island east of New York City. "It was really quite enhancing and entrancing, it was very fascinating to me."
