Pseudoscorpions are tiny creatures (just a few millimeters in length) that look similar to real scorpions but lack the large 'stinger' tail. Due to their small size they are harmless to humans and pets but are fierce predators of small insects, springtails and other small arthropods. Pseudoscorpions posses two long pincers (pedipalps), which are used to catch and inject venom into their prey. They can also use their claws to hitch a ride on larger insects, such as flies, to move to new locations.
You can find pseudoscorpions in many habitats but particularly in leaf litter, moss, under tree bark and stones. However, they are not easy to find as they prefer to hide in small cracks and crevices out of sight. To date I've only found a handful of pseudoscorpions with perseverence and a good eye required to spot them.
