.They're back: 17-year cicadas to swarm from Georgia to New York

HAMDEN, Connecticut (Reuters) - Colossal numbers of cicadas, unhurriedly growing underground since 1996, are about to emerge along much of the U.S. East Coast to begin passionately singing and mating as their remarkable life cycle restarts.

This year heralds the springtime emergence of billions of so-called 17-year periodical cicadas, with their distinctive black bodies, buggy red eyes, and orange-veined wings, along a roughly 900-mile stretch from northern Georgia to upstate New York.

The eerie, cacophonous mating music they produce, along with the unusual synchronous mass emergence and lengthy development cycles, have amazed scientists and lay people alike for centuries.

In central Connecticut, particularly dense concentrations of so-called Brood II cicadas, named Magicicada septendecim, should arrive in late May or June, says Chris Maier, entomologist with the Connecticut Agricultural Experiment Station in New Haven.

This will be Maier's third time studying their emergence - he tracked them in 1979 and again in 1996. He said they are next due in 2030, when he will be 81 years old.

Maier said the first scientific recording of Brood II specimens was in 1843.

The precisely-timed arrival of the 1.5-inch (38-mm) plant-sucking, flying adults takes place after a lengthy period of development underground as juveniles.

After maturing, males begin what cicadas may be best known for: their conspicuous acoustic signals, or "songs," to sexually attract females.

Should be a holiday. The stay inside and read a book and look out the window day!

Now if we could just train them to eat liberals.

Mystery Cicada Swarms Emerge Across Maryland In 2017
May 16, 2017 - Cicadas are supposed to stick to a 13- or 17-year cycle, but swarms have emerged this spring. Why are they showing up across Maryland?
Quote:
A deafening and somewhat nasty phenomenon that longtime Marylanders will recognize has popped up this spring. Cicadas, sometimes known as "17-year locusts," have emerged in big numbers in Columbia, Bowie, Annapolis, Rockville and College Park, as well as across Washington, D.C., and northern Virginia in the past week, says one expert. The bugs, which, in large numbers can do serious damage to young trees, shrubs and various crops, are always around. But huge broods of them occasionally hatch all at once, usually in 13-year and 17-year cycles. For reasons that scientists are still trying to determine, a brood of cicadas will hatch in off years, which is the case for Maryland and Virginia. (SIGN UP: Get Patch's Daily Newsletter and Real Time News Alerts. Or, if you have an iPhone, download the free Patch app.)

According to The Gardener's Network, a 17-year brood known as Brood VI hatched last month in Georgia, North Carolina and South Carolina. But Michael Raupp, a University of Maryland entomologist known as The Bug Guy, writes on his latest blog that what experts call "periodical" cicadas may be part of Brood VI, which hatched in 2004 in Maryland, or they could also be an early wave of Brood X, which is due to hatch in 2021. Theories on the mysterious appearance of the bugs clinging to trees and leaving exoskeleton shells everywhere includes a link to climate change, Raupp said. The numbers of cicadas out in Maryland is expected to increase as temperatures rise close to 90 degrees this week. “We don’t know exactly why this happens. All we know is that it does happen,” Raupp told WTOP.


With temperatures climbing this week, "the entire DMV region should be rocking with these teenagers by next weekend," Raupp says. "So, grab a flashlight and look for a cicada jail break at night, and by day watch the antics of these amazing creatures as the big boy band cranks up in the treetops." The early visit by Brood X is known as acceleration, he says, when a portion of a cicada brood emerges years in advance of the "billions of cicadas comprising the bulk of their ginormous synchronous brood," Raupp writes.

In 2016, periodical cicadas in some areas hit densities of 1.5 million insects per acre, according to the Washington Post. Fortunately, the adult life span of a cicada is short. The young nymphs often land on trees to shed their skin and become adults. After that, they spend only about four to six weeks above ground before dying. Contrary to popular belief, adult cicadas do not eat the vegetation that comes into their path. Rather, adult females cut slits into twigs and small branches to lay their eggs. The eggs hatch, creating tiny nymphs, which fall to the ground and burrow, feeding on underground tree roots for years until it's their time to emerge.
