**ADVANCE FOR MONDAY, MAY 21 - FILE** An adult cicada climbs a tree in Princeton, N.J., in this June 1, 2004, file photo. The red-eyed, shrimp-sized, flying insects, which should be appearing soon, don't bite or sting. But they are known for mating calls that produce a din that can overpower ringing telephones, lawn mowers and power tools. (AP Photo/Daniel Hulshizer, File)
