"ManhattAnts" are taking over New York City. Researchers have finally identified the invasive insects.

The invasive "ManhattAnt" has been infiltrating New York City since 2011, worrying scientists – who have finally figured out what species the larger-than-average, black-and-red ant is. Since the giant ant showed up in the heart of New York City, its population has started to spread and, like other pests, it could cause ecological harm. 

There is no record of the ManhattaAnt in the 2009 survey of New York City ants, and when the insect was first observed, it had a relatively small population, mainly sticking to parks. But now, it is one of the most common ants in the area and each year its population has expanded about 1.2 miles – taking this species across the Hudson River to New Jersey. 

While the concrete jungle might not seem like the optimal breeding ground for invasive species, several have thrived in the city, including the Asian long-horned beetle.
