NEW YORK (AP) - The High Line, a park that turned a dilapidated stretch of elevated railway on Manhattan's West Side into one of New York's newest tourist attractions, may have brought a different kind of visitor: a cockroach that can withstand harsh winter cold and never seen before in the U.S.

Rutgers University insect biologists Jessica Ware and Dominic Evangelista said the species Periplaneta japonica is well documented in Asia but was never confirmed in the United States until now. The scientists, whose findings were published in the Journal of Economic Entomology, say it is too soon to predict the impact but that there is probably little cause for concern.

"Because this species is very similar to cockroach species that already exist in the urban environment," Evangelista said, "they likely will compete with each other for space and for food."

That competition, Ware said, will likely keep the population low, "because more time and energy spent competing means less time and energy to devote to reproduction."

Michael Scharf, a professor of urban entomology at Purdue University, said the discovery is something to monitor.

"To be truly invasive, a species has to move in and take over and out-compete a native species," he said. "There's no evidence of that, but that doesn't mean we shouldn't be concerned about it."

The newcomer was first spotted in New York in 2012, by an exterminator working on the High Line.

The scientists suspect the little critter was likely a stowaway in the soil of ornamental plants used to adorn the park. "Many nurseries in the United States have some native plants and some imported plants," Ware said. "It's not a far stretch to picture that that is the source."

Periplaneta japonica has special powers not seen in the local roach population: It can survive outdoors in the freezing cold.

"There has been some confirmation that it does very well in cold climates, so it is very conceivable that it could live outdoors during winter in New York," Ware said. "I could imagine japonica being outside and walking around, though I don't know how well it would do in dirty New York snow."

The likelihood that the new species will mate with the locals to create a hybrid super-roach is slim.

"The male and female genitalia fit together like a lock and key, and that differs by species," Evangelista says. "So we assume that one won't fit the other."

    Federal authorities to monitor Newark police

    Tuesday, July 22 2014 9:37 PM EDT2014-07-23 01:37:12 GMT
    Newark police engaged in the excessive use of force, routinely stopped people on the street for no legitimate reason and regularly stole property from civilians, the U.S. Department of Justice concluded in a report released Tuesday that set the stage for federal monitoring of the police department that serves New Jersey's largest city. The report is the culmination of a three-year investigation begun months after the American Civil Liberties Union filed a complaint.

    White flags raised at Brooklyn Bridge

    The NYPD is investigating a major security breach at the Brooklyn Bridge, one of the most highly secured landmarks in New York City. Two white flags — international symbols of surrender — fluttered from poles on the stone supports that hold cables above the bridge connecting Brooklyn and Manhattan. The flags had a faint appearance of the stars and stripes. The American flags that are normally up at the bridge appeared to have been removed.
