NY City has created its own ant species

I don't know if the newest species of ants use their chemical signals and antennas to say, "Hey, I'm WALKING here!" but they are denizens of New York City. In fact, they have a very restricted range reported as "traffic medians on Broadway between 63rd and 76th streets." Aside from the burning question of whether these creatures are Giants or Jets fans, it appears to be an example of adapting to a very specific environment. Insect species endemic to tiny environments, such a single tree, may be common in Brazil, but they don't normally emerge from US cityscapes. Or maybe they are normal, and we just haven't looked enough.
