After 17 years spent alone underground, billions of red-eyed cicadas are emerging for their final act: to meet a partner, breed and die. Upon emerging, the insects blanket the trees and ground with the males filling the air with buzzing and whistling to attract females. But that sound also brings tourists and scientists to study this rare event. With air temperatures and surface soils warming from climate change, scientists are also keen to learn how the creatures are responding. Temperatures affect when cicadas emerge and their underground growth. Scientists witnessed large numbers of 17-year cicadas surface years ahead of schedule in 2017, which entomologists suspect could be related to global warming. The biggest questions are: Is climate change changing their life cycles? And then, how does it change them? said Chris Simon, an evolutionary biologist at the University of C ....
