Nearly 3,400 species of cicadas exist worldwide. But periodical cicadas that emerge once every 17 or 13 years are unique to the eastern US. The 17-year cicadas live in the North, and the 13-year cicadas are found in the South and the Mississippi Valley. As they surface, some of these cicadas will become prey to the animals nearby, but with the crazy population of these cicadas, eventually, animals stop consuming them. The surviving cicadas, which also range in billions start singing their very own mating song which can reach as high as 100 decibels and sound similar to a chainsaw or a lawnmower. Cicadas don’t survive after mating; the females put their eggs in trees and perish in a few moments. These eggs then hatch after some time and then fall to the ground. At this time these newborn cicadas dig into the Earth and go towards the trees to chew on the tree root for nearly 17 years until they are ready to re-emerge. The broods are identified by Roman numerals. Brood X is the largest of the 12 broods of 17-year cicadas, which emerge in different years.
People and restaurants across US are including cicadas in recipes for dishes such as sushi, tacos and even dessert. These insects are believed to be low in fat and high in protein.
