Americans on average share their homes with 100, and up to 211, different types of tiny animals known as arthropods, according to a new study.
The study, published in the journal PeerJ, is the first to evaluate the biodiversity of such little creatures in U.S. homes. Arthropods are animals that have protective external coverings, segmented bodies and jointed limbs. They include insects, spiders, mites, centipedes and more.
"I was surprised by the number of specimens we collected from very typical homes, as well as how many rooms we found them in," lead author Matt Bertone told Discovery News. "For instance I didn't expect some groups to be in every home we sampled, and I would not have expected, for example, cobweb spiders to be found in 65 percent of rooms."
Bertone, an entomologist at North Carolina State University, and his colleagues also found a lot of ants, such as this search party of little black ants that succeeded in finding a morsel of food on a couch.
He explained, "A variety of ants (Formicidae) can commonly be found in homes. These social insects often form trails of workers looking for food and water."
