The splash of jumping into a pool.

The clink of ice cubes in lemonade. The whisper of swaying tree leaves. Probably the rhythmic and incessant chirping of cicadas, a common summer tree pest. If you hear or see cicadas in your yard, are they just annoying, or can they do damage? There are two types of cicadas: annual cicadas also called dog day cicadas and periodical cicadas also known as 13 or year cicadas. Periodical cicadas live underground for either 13 or 17 years and emerge in either May or June.

Annual cicadas come out later in the year July and August and stick around for about 2 to 4 weeks. Instead, they create slits in tree branches to lay their eggs. Those splits weaken the tree over time, and later, you could see those branches breaking, withering or dying.

They have bright red eyes and clear, membranous wings with black veins. Each brood of periodical cicadas has a specific range, but all are found in the eastern and midwestern United States. Periodical cicadas are associated with deciduous trees and shrubs.

They sometimes cause harm to young trees, but this can easily be prevented by covering the plants with cheesecloth until the adults die out. Cicadas are mostly beneficial. They prune mature trees, aerate the soil, and once they die, their bodies serve as an important source of nitrogen for growing trees. The fact that cicadas emerge in the millions, however, makes them relatively resilient to predation.

Even when a ton of them are eaten, there are still plenty more ready to mate and lay eggs. Cicadas have modified mouthparts to feed on liquids rather than solid material. Larvae suck juices from plant roots, while adults suck fluids from woody shrubs and trees. Periodical cicadas are best known for their extraordinary, highly synchronized life cycles.

They spend most of their lives—13 or 17 years, depending on the species—in larval form, burrowed beneath the soil and feeding on fluids from plant roots. In springtime, they emerge from the soil and complete their final molt into adulthood.

Each individual in a brood emerges within weeks of one another. Males cluster in groups and produce loud choruses to attract females to mate with. After mating, female cicadas excavate furrows in slender tree branches and deposit their eggs. The larvae hatch, drop to the ground, and burrow beneath the soil again. Cicada nymphs suck sap from the xylem of various tree species. Post-coitus, the female cicada cuts slits into the bark of a twig and deposits her eggs, repeating the process until she has laid several hundred eggs.

When the eggs hatch, the nymphs drop to the ground and burrow. This year is Brood II, which has a year life cycle that is soon coming to an end. These nymphs have spent nearly two decades feeding on roots, and will burst into a mating frenzy once the ground temperature reaches 64 degrees Fahrenheit.

The red-eyed insect will outnumber people living from North Carolina to Connecticut by to 1. Although benign to humans they do not bite or sting , cicadas have been known to mistake an arm for a tree or plant limb and attempt to feed. Adult cicadas have a long proboscis which they use to feed on sap from plant stems. Cicadas can cause damage to crops, shrubs, and trees typically in the form of scarring left on branches while the females lay their eggs deep in the branches.
