Brood XXII is one of three extant broods of 13-year cicadas. Brood XIX is one of three extant broods of 13-year cicadas. Brood XIV is among the 12 different broods with 17-year cycles. Brood XIII is among the 12 different broods with 17-year cycles. Brood XIX is one of only three surviving broods with a 13-year cycle. Brood II is among the 12 different broods with 17-year cycles. The female broods the chicks during the first four days after hatching. The female broods the chicks for up to seven days after hatching. As the nestlings grow, the female broods them, and later on assists in providing food. Two broods, sometimes three, maybe reared in a season. In this role they feed and care for subsequent broods and repel cuckoos or predators. To compensate, shrub nesters must have more broods and shorter nesting times. Cicada broods may also have a negative impact. The female salamander often broods the eggs. Cannibalism amongst broods rarely occurs in this species generally.
