Brood X Cicadas Set to Emerge in 2021
What You Need to Know About the Brood X Cicadas
17-Year Cycle Returns
Mark your calendars: the Brood X cicadas are set to emerge in 2021. These insects, which have a 17-year life cycle, were last seen in 2004. This year, they are expected to emerge in vast numbers across the eastern United States.
Brood X is the largest and most widespread of the periodical cicada broods. It covers an area of over 15 states, from Georgia to New York and as far west as Illinois.
Life Cycle and Behavior
Cicadas spend most of their lives underground as nymphs. They feed on tree roots and grow slowly. When the time is right, they emerge en masse and molt into adults. The adults then have just a few weeks to mate and lay eggs before they die.
Cicadas are known for their loud, buzzing song. The males sing to attract mates. The females respond by clicking their wings, which creates a rhythmic sound.
Impact on Trees and Plants
Cicadas can damage trees and plants by laying their eggs in the twigs. However, the damage is usually not severe. In fact, cicadas can actually benefit trees by aerating the soil and adding nutrients.
Preparation and Precautions
If you live in an area where Brood X cicadas are expected to emerge, there are a few things you can do to prepare:
- Protect young trees and plants by covering them with netting or burlap.
- Avoid using pesticides, as they can harm cicadas and other beneficial insects.
- Be aware of the potential for traffic delays, as cicadas can slow down traffic when they emerge in large numbers.
