17 Year Cicada: 17 Year Cicada Area - The term "a periodical cicada" commonly refers to as "a 17-year-old locust". There is even a biblical story of awful locust plagues both in Egypt and Palestine. The periodic appearance of locusts was considered evil significance. That is why modern cicadas are called locusts.
Mature nymphs of periodical cicadas begin burrowing upward after 17 years of soil living on the depth of 2-24 inches. This is April, when they actually stop and wait for the proper emerging time. Their muscle structure undergoes major changes at this time.
