A guide to pseudoscorpions in New York

As an avid arachnid enthusiast, I’ve spent countless hours observing and studying these fascinating creatures in their natural habitats. It’s quite intriguing to note the diversity of these creatures across various environments. Today, I’d like to delve into a peculiar question that I’ve often been asked, “Are there pseudoscorpions in New York?”

Are There Pseudoscorpions in New York City?

When one thinks of New York City, it’s usually the iconic skyline, the diverse cuisine, or the bustling streets that come to mind. But beneath this urban facade, there’s a world teeming with a different kind of life.

Yes, you read that correctly – pseudoscorpions do reside in New York City! These miniature arachnids favor less glamorous, hidden corners of the urban sprawl. Basements, storerooms, and even bookshelves can serve as homes to these intriguing critters.

Obviously if you’ve been to New England during the winter, you’ll probably be thinking that it’s simply too cold for such an exotic-looking arachnid.

Whilst it is true that these arachnids are most diverse in the tropics, they do tolerate cold quite well. They have a global distribution, and can even be found in parts of Canada and southern Alaska. It is thought that they exploit hiding places deep in the ground, or hidden corners of buildings to survive freezing conditions.

Some species will also hide in a silk cocoon, giving them additional protection from harsh winter conditions.

Are There Pseudoscorpions in New Jersey?

Now, let’s switch gears and look at New Jersey. You’ll be pleased (or perhaps surprised) to know that these miniature arachnids aren’t exclusive to the Big Apple. In New Jersey, just like in New York City, pseudoscorpions can be found in homes and gardens, quietly going about their business.

Overall, you can expect to find pseudoscorpions in even the most northerly states of the US. They live in all of New England, but they also live in Michigan, Minnesota, and even Alaska.

Where Are Pseudoscorpions Found?

You might be wondering, where else can these interesting creatures be found? Well, pseudoscorpions are more common than you might think! They can be found worldwide, in diverse habitats from the rainforests to the Arctic. In urban environments, they often reside in human dwellings.

Generally speaking, they do well indoors, and may enter homes when it starts to get cold outside as a way of seeking warmth.

House Pseudoscorpion

The house pseudoscorpion (Chelifer cancroides) is the most commonly encountered species in our homes. Though they may look a little intimidating with their scorpion-like pincers, they are, in fact, beneficial house guests.

These helpful critters prey on various household pests like moth larvae, ants, and small flies. In fact, they’re so good at it that they now have a cosmopolitan distribution, literally living on most of the world’s land masses.

Pseudoscorpion Size

Despite their fierce appearance, pseudoscorpions are rather small in size. They typically measure between 2 to 8 millimeters in length. Their most distinctive feature, the front pincers, make them easily recognizable, despite their small stature.

The main thing limiting their size is what ecologists call their niche. The pseudoscorpion niche is that of a hunter of tiny prey. If they were any bigger, they’d have to adapt to hunt different prey, and they’d end up competing with spiders.

Do Pseudoscorpions Bite?

Here’s some good news for those of you who might be feeling a little uneasy about the idea of pseudoscorpions in your home. These little critters are harmless to humans. They do not bite or sting and their pincers are too small to puncture human skin.

More to the point, they have no interest in harming us, and haven’t adapted to suck blood or anything like that. They literally just want any bugs that might be hiding in our homes.

How can pseudoscorpions be helpful to humans?

How Pseudoscorpions differ from Real Scorpions

Although they share a part of their name and some physical similarities with real scorpions, pseudoscorpions are distinctly different:

  1. Size: Pseudoscorpions are significantly smaller.
  2. Anatomy: Unlike scorpions, pseudoscorpions lack a tail and stinger.
  3. Habitat: Pseudoscorpions can adapt to cold climates, unlike their desert-dwelling counterparts.
  4. Behavior: Pseudoscorpions are non-venomous and harmless to humans.

How Pseudoscorpions differ from Ticks and Mites

Due to their small size, pseudoscorpions are often mistaken for ticks or mites. However, they can be differentiated based on a few key features:

  1. Legs: As arachnids, pseudoscorpions possess eight legs, while ticks and mites have six.
  2. Body Structure: Pseudoscorpions have a two-segmented body with prominent pincers, unlike ticks and mites.
  3. Behavior: Ticks are parasitic and feed on the blood of hosts, while pseudoscorpions are predatory and feed on small arthropods.

Pseudoscorpions in New York. Final Thoughts…
