periodical cicada

sustantivo

An American cicada whose nymphs emerge from the soil in large numbers periodically. The mature nymphs of the northern species ( seventeen-year locust) emerge every seventeen years; those of the southern species emerge every thirteen years. A cicada brood can be so abundant that the shrill sound emitted by the males can damage the human ear.
