Cicada juveniles are called "nymphs" and while living that 13 or 17 years underground, they suck root fluids for food. So they are not in "hibernation" or such,. They have five juvenile stages in their underground burrows, with each stage ending with eclosion (shedding of the old nymphal skin). Close to their time to emerge, they dig tunnel from the underground. http://insects.ummz.lsa.umich.edu/fauna/michigan_cicadas/Periodical/Index.html
