There can be as many as 1.5 million cicadas per acre, bringing the total brood population into the billions. Having spent almost two decades underground in their immature “nymph” state eating tree root sap, the bugs will crawl out in mid-May to late-June when soil hits 64 degrees Fahrenheit – likely

after a sprinkling of warm rain. Once above ground, the insects will set about mating, the noise of their mating call can hit 100 decibels, and lay their eggs before dying, according to the Rutgers NJAES’ Department of Entomology. According to Joe Zoltowski,

director of the New Jersey Department of Agriculture’s Division of Plant Industry, New Jersey hosts populations of two broods (Brood II and X). This year, Brood X is expected. Brood X is neither the easternmost nor the largest of the broods in the United States. Even so, this brood is among the largest (by geographic extent) of the 17-year cicada population. Cicadas emerge after these long time periods exclusively for mating purposes. After mating, females lay eggs on small branches on deciduous trees, which become structurally unsound and can break off and fall during windy days. The larvae crawl to the ground and burrow underground, feeding on roots of trees and plants to eventually emerge again, thereby completing their life cycle. These insects do not harm people or animals and provide an abundant food source for natural wildlife when their emergence occurs. They provide beneficial results like soil aeration and pruning activities to mature trees, and to the ecosystems they occur in, decomposition adds nutrients back to the soil. Rarely do they cause tree mortality, despite adults feeding on the leaves of the trees during the emergence (Cont. on Page 4) period.
