The origin of some of the astronomical cicada numbers can likely be traced to evolution, Cooley and several other entomologists said. Fat, slow and tasty, periodical cicadas make ideal meals for birds, said Raupp, who eats them himself. (His school put out a) But there are too many for them to be eaten to extinction, he said.

“Birds everywhere will feast. Their bellies will be full and once again the cicadas will emerge triumphant,” Raupp said.The other way cicadas use numbers, or math, is in their cycles. They stay underground either 13 or 17 years, both prime numbers. Those big and odd numbers are likely an evolutionary trick to keep predators from relying on a predictable emergence.The cicadas can cause problems for young trees and nurseries when their mating and nesting weighs down and breaks branches, Shrewsbury said.

Periodical cicadas look for vegetation surrounding mature trees, where they can mate and lay eggs and then go underground to feast on the roots, said Mount St. Joseph University biologist Gene Kritsky, a cicada expert who wrote

Here’s a closer look at the facts.CLAIM: An ICE van in Philadelphia seen ablaze in a video spreading online was intentionally set on fire by left-wing extremists.
