What do cicadas eat?

CICADA insects belong to the Hemiptera order and have about 3,000 species around the world.

The periodical insects typically emerge between July and August after 17 years of hiding underground.

What do cicadas eat?

Cicadas are herbivores, meaning that they eat vegetation. 

Young cicadas eat liquid from plant roots, while molting cicadas eat twigs. 

Adult cicadas do not feed, according to the US Department of Agriculture.

Cicadas are not known to cause harm to vegetation or crops when they feed.

When do cicadas come out?

Cicadas emerge from underground with certain temperature conditions. 

When the ground temperature is at a depth of 8 inches and reaches 64 degrees Fahrenheit,  the cicadas begin to make their way above ground, according to the National Oceanic and Atmospheric Administration.

The most studied cicadas are six periodical species belonging to the genus Magicicada, according to the University of Michigan. 

Three species have 13-year cycles, and three have 17-year cycles.

There are more than a dozen cicada broods all over the eastern half of the US, all on different 13-17 year schedules.

Are cicadas endangered species?

No species of cicadas are endangered, yet there are some that are at risk.

According to the International Union for Conservation of Nature (IUCN), the Cassini periodical cicada, the Decim periodical cicada and the Decula periodical cicada as lower risk/near threatened.

It is unclear as to why those specific species are at risk.

Over a million insects can inhabit a relatively small area of land. 

A group of periodical cicadas that emerge at the same time is called a brood. 

Broods are classified with Roman numerals that represent each group. 

There are 30 broods in all and for 2021, the brooding type will be known as BroodX (pronounced ten).
