NYC is full of undiscovered species — and we’ve hatched a plan to find one

It starts with setting up big bug traps in two of the city’s most iconic parks.

New York City is one of the most well-explored places on Earth.

Established nearly four centuries ago by an influential Dutchman, the city has since grown into the largest and most densely populated metropolis in the country, with no fewer than 28,000 people per square mile, or about one person per 1,000 square feet. People are everywhere.

That’s what makes this so astonishing: Scientists believe there are almost certainly hundreds, if not thousands, of undiscovered animal species living in the middle of New York, among the city’s parks, gardens, and streets. I’m not talking about the big stuff — birds, frogs, and so on — but small critters, including flies, wasps, and other insects.

It’s not that NYC is some sort of global bug hot spot. (Despite what it might feel like in the summer, it is not.) Rather, the bulk of species in many insect groups, wherever they’re found, remains unknown. As one example, there may be as many as 1.8 million species globally in a single fly family called Cecidomyiidae, known as the gall midges. Yet only about 7,000 of them have been described in the scientific record and are thus known species. Broadly speaking, taxonomists estimate that as much as 90 percent of all animal species on Earth are still unknown. That is, of course, nearly all of them.

This summer, Vox is setting out to play a small role in filling these giant gaps in the global tree of life — by trying to discover a new species, right here in New York. It’s a goal we understand........
