Although they look like really small scorpions, Pseudoscorpions lack a tail or stinger. They have venom glands in their claws meant to kill tiny mites and springtails. They are so small, however, they pose no threat to humans and would require a magnifying glass in order to get a really good look at them and their prey.
Because they do not have wings, traveling long distances can be an ordeal. Their small size allows them to catch free rides on larger insects, like beetles and even flies, without notice.
Some species are blind, but even those with sight aren't able to see well. They use their claws like antennae, feeling and touching their surroundings to find their way around.
They do make their own silk , but not to spin webs or catch prey like a spider. Instead, they build cocoons in which they spend cold winters.
Pseudoscorpions can be found in a variety of places: between book pages, at the water's edge, in caves, woods, under rocks and maybe even in a house. If you happen to find one, leave it to its work of eliminating small pests from the area.
