Nell Greenfieldboyce, an NPR science correspondent and expert on ant behavior, dives into the surprising takeover of European ant species in New York City. She discusses how this unremarkable species has thrived in an urban environment since 2011. The conversation uncovers the unique traits that enable the MahattAnts to adapt, their ecological impact, and the role of citizen science in researching these invasive critters. Get ready to rethink what you know about ants and urban ecosystems!
The MahattAnt's rapid spread throughout New York City since 2011 showcases its remarkable adaptability to urban environments.
The ecological implications of the invasive Manhattan ant include potential disruptions to native species and city tree health due to increased aphid populations.

The Mysterious Manhattan Ant
A new ant species, identified only recently, has established itself in New York City since its arrival in 2011. Initially, researchers were puzzled by this ant's presence and even unsure of its species, as it was previously undetected in earlier surveys. Over time, it became evident that this distinctive ant, which features a reddish midsection, began to spread throughout Manhattan and into the outer boroughs. Its unique characteristics and the ability to thrive in urban environments have made it a subject of interest for both scientists and the public.
Surprising Adaptation and Movement
The Manhattan ant displays remarkable adaptability, thriving in various urban settings and even infiltrating high-rise buildings, which is unusual for ant species. Researchers have noted its rapid movement on city sidewalks, where it is competing with the long-established pavement ant for dominance. This invasive species is migrating at a rate of about a mile each year, potentially spreading further along the East Coast. Specimens have already been spotted across state lines, indicating its capacity for colonization and expansion beyond New York City.
Ecological Implications of the Invasion
The ecological impact of the Manhattan ant's invasion remains uncertain, raising questions about its interactions with native species and urban ecosystems. While it primarily feeds on honeydew excreted by aphids, there is a concern that its presence could lead to increased aphid populations, impacting city trees. The ant's competition with native ant species could disrupt crucial ecological functions they provide, such as seed dispersal. As researchers continue to monitor this phenomenon, the potential consequences of the Manhattan ant's establishment in New York and beyond remain a topic of active investigation.
New York: The city that never sleeps, the concrete jungle where dreams are made of and more recently ... home to a mysterious ant spreading across the city — before continuing across metropolitan and even state lines. NPR science correspondent Nell Greenfieldboyce joins host Regina G. Barber to trace the MahattAnts' takeover, explain why they're an interesting invasive species case study. Plus, how everyday people can get involved in research efforts to learn more about these critters.
