Backyard bug-watchers are seeing the winged bugs known as cicadas come out of their holes in New Jersey and North Carolina after 17 years of underground slumber — and scientists say a full-scale outbreak may not be far behind.
"There are some pretty convincing reports coming out," John Cooley, an expert on cicadas at the University of Connecticut, told NBC News. "It's fair to say it's starting, but it's still in the very early stages. It certainly isn't going all crazy. ... When it really happens, it's not going to be like this. It's going to be shovel loads of cicadas."
Cooley maintains one of the most closely watched websites for this spring's emergence, Magicicada.org. Little bug logos are popping up on different areas of Magicicada's interactive map, which means a smattering of Internet users are seeing cicadas coming out of the ground. In some cases, they're even seeing the bugs crawling around as adults.
Cooley, however, says that we ain't seen nothing yet. "When it really happens, we expect that website will just light up," he said.

Cicada song
Male cicadas have loud noisemakers called "tymbals" on the sides of the abdominal base. Their "singing" is not the stridulation (where one structure is rubbed against another) of many other familiar sound-producing insects like crickets: the tymbals are regions of the exoskeleton that are modified to form a complex membrane with thin, membranous portions and thickened "ribs". Contracting the internal tymbal muscles produces a clicking sound as the tymbals buckle inwards. As these muscles relax, the tymbals return to their original position producing another click. The interior of the male abdomen is substantially hollow to amplify the resonance of the sound. A cicada rapidly vibrates these membranes, and enlarged chambers derived from the tracheae make its body serve as a resonance chamber, greatly amplifying the sound. The cicada modulates the sound by positioning its abdomen toward or away from the substrate. Additionally, each species has its own distinctive "song".
