[2] A May 2024 report published in Biological Invasions details the rapid spread of the so-called "ManhattAnt" since its initial appearance in New York City in 2011.

This invasive species is expanding its territory at an estimated rate of approximately one mile per year, raising concerns among researchers about potential ecological disruptions across the East Coast.
