Will cicadas wreak havoc on your company's manufacturing plant next spring?
I was on my patio the other day, soaking up what is left of autumn in Illinois, and I noticed something was missing -- and not just the leaves off the trees. It was the absence of the loud buzzing noise I had heard at the beginning of summer. Until recently, I thought this noise came from a bird. I learned, however, that an insect, a cicada, is responsible for the long-lasting background buzz many of us hear from May through July.
According to the University of Michigan Museum of Zoology Insect Division, cicadas have multiple-year life cycles and come in many varieties, some of which appear each year and others that appear periodically in 13- and 17-year cycles. Those that appear every 13 years generally can be found in the Midwest and South while the 17-year cicadas are found mostly in the North.
