Over 1 Trillion Cicada Bugs To Emerge This Spring From 17-year Hibernation Cycle
According to entomologist Gary Parsons, the Brood X cicada bug is due to come out of their deep cycle 17-year hibernation cycle come mid-May in Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Washington, D.C. The several trillion that will dig their way up from in the ground where they feed on tree roots are expected to populate as much as 1,000 per acre in some areas.
The noise they make by rubbing their wings together usually starts in the evenings and can reach as high as 100 decibels. They are triggered to come out of hibernation when the ground temperature reaches 64 degrees, but can not survive in the air if temperatures dip below 68. Other types of cicada broods hibernate at different cycle lengths ranging from 3 or 4 years to 13 years and 17 years and can be found in other parts of the country.
Scientist think this behavior was developed by Cicadas to defend against predators and to ensure their numbers are so high the they can’t be wiped out. Because cicadas feed on tree roots, it is advised that you do not plat new tree seedlings this summer as once the cicada bugs go back underground for anywhere 17-years, they will feed on tree roots and can kills newly planted trees.
Cicada bugs are not poisonous, they don’t bite or sting, nor do they leave smelly residues. Occasionally dogs get sick from eating them, but according to veterinarians, it's because they ate too many.
