I find pseudoscorpions most often when I am sorting soil samples for tiny snail shells under a bright light in the lab. They are fascinating creatures and I would love to watch them in their natural surroundings, but their usually dark colored tiny bodies would be very hard to spot on dark soil in dimly lit forests. Moreover, according to Weygoldt1, pseudoscorpions spend most of their lives in small crevices and seldom appear on open ground. I have also occasionally found them in containers of empty snail shells, which indicates that they hide in empty snail shells. The individual pictured here was from a soil sample that I collected last weekend.
This specimen was less than 2 mm long.
Pseudoscorpions made their debut on this blog in a previous post. If I had more time on my hands, I would learn how to identfify them and study their zoogeography.
More information on pseudoscorpions by Mark Harvey, a world authority on them, is available here.
This page has links to images of British pseudoscorpion species and to past issues of Galea, a pseudoscorpion newsletter.
Tree of Life has a list of references on the evolution and phylogeny of Arachnida, the class to which the pseudoscorpions belong.
