17 Year Cicada: 17 Year Cicada Larvae - Periodical cicadas are native and the longest-lived North American species. No other insect here generates so much interest. They do not occur anywhere else in the world!
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.
