Long Island went from idyllic farmland to completely urbanized in 75 years, thanks in part to Robert Moses inability (or unwillingness) to comprehend that any form of transport existed except automobiles. Massive, car-driven development spread inexorably down the Northern and Southern State Parkways, and the Long Island Expressway, covering all those farms and forests with concrete and Walmarts. Even when I spent four years of college there in the early 1990s, one could still find open space east of Ronkonkoma.
Alas, in the past 17 years, all that open space has disappeared, and with it the Brood X cicadas:
Development, pesticide use and the presence of invasive species are destroying historic populations of Brood X cicadas, while climate change spurs bugs from different broods to come up years early, experts say. The disruption of these cycles means some places that were expecting cicadas this year will miss out, while others may be surprised by an unscheduled emergence.
Although these changes are likely happening across the cicadas’ range, they’re particularly visible on Long Island, said Chris Simon, a professor at the University of Connecticut who has been studying cicadas for over 40 years. Long Island was once New York’s last remaining stronghold of Brood X. But the population there has declined in recent decades, and was nearly absent during the last mass emergence in 2004. At the same time, some of the area’s Brood XIV cicadas — scheduled to come up four years from now — may make an early appearance this year instead.
In the past, Long Island has been the easternmost place that can lay claim to this eminent brood. As far back as 1902, New York’s state entomologist recorded Brood X cicadas in both Suffolk and Nassau counties, said Dr. Simon, who has been studying cicadas on Long Island for over 40 years. Their reign continued through 1987....
The brood was absent from more places where it was expected, including in the towns of Shirley and Oakdale, and made only a brief showing in other locations, such as Connetquot State Park, a 3,700-acre reserve south of the Long Island Expressway, said Dr. Simon. Steep declines like this often lead to a complete disappearance, she said — without strength in numbers, the whole population can be devoured.
This year, Dr. Simon and other researchers are encouraging people in and around Long Island to go searching for the insects, and to use an app, Cicada Safari, to report any findings. If they do show up, it will likely be in early June. But she is not optimistic. “I’m afraid that they’re going to be completely gone,” she said.
Chicago's Brood XIII should emerge in three years. I can't wait. At least here, we haven't destroyed their habitat as thoroughly as Nassau and Suffolk Counties have destroyed Brood X's.
