It's Just Our Turn. There are 15 groups â or broods â of cicadas that are on life cycles of either 13 or 17 years. They appear mostly in the eastern and central parts of the U.S. Last spring, it was a brood in parts of Texas, Oklahoma, Missouri, Kansas, Nebraska and Iowa that had its coming out.
After 13 or 17 years, mature cicada nymphs emerge at any given locality, synchronously and in tremendous numbers. After such a prolonged developmental phase, the adults are active for about 4 to 6 weeks. The males aggregate into chorus centers and attract mates.he nymphs of the periodical cicada undergo 5 instar stages in their development underground. The difference in the 13 and 17 year life cycle is the time it takes for the second instar to mature.
