I guess we have all heard about the plague of Cicadas in the east by now, espessially if you are among the few who are actually living them. But that is it about these little buggers that make them so popular... or infamous?
Cicadas are insects, they go by the scientific name Magicicada... sort of. There are numerous different Genus of cicada out there, but the cicadas that we are dealing with in the east coast, also known as Periodical Cicadas, are of the Genus Magicicada. They are called Periodical Cicadas because they only arise from the ground every 17 years numbering in the billions (these are called broods); and then they mate, lay their eggs, and die very soon afterwords.
It takes about 2 weeks for them all to finish emerging; and after they emerge, the typical lifespan of the cicada is only about 4-6 weeks, if that. Most cicadas die from being eaten by birds and other animals, squashed on windshields, stepped on, run over, etc.
The buzzing and croaks of the cicada is be rather deafening if they batch into large groups, called plagues. The noise only comes from the male cicadas, so imagine what it'd be like if the females called as well.
There are two different branches of cicada as well: Periodical Cicadas, which come around every 14-17 years, and Annual Cicadas, which appear every 2-8 years and can be seen frequently.
These little bugs will not last for very much longer, so enjoy them while they last! ... or at least try to.
