Pseudoscorpions are a type of arachnid, meaning that they are not insects, but are closely related to spiders. They are named “Pseudo” scorpions because they have pincers that resemble scorpions, but do not have a tail and stinger. They can be found anywhere from a tree canopy, to somewhere in your home where they feed on the larvae of some household pests. They can also be found in leaf litter, where they feed on other tiny arthropods. Males use chemicals known as pheromones, and a fancy dancing behaviour, to attract females to mate. These arachnids construct a silken cocoon which they use to protect themselves during the winter. Pseudoscorpions occur all over the planet, but are rarely collected in Malaise traps. In total, only one specimen was collected during the Fall 2014 School Malaise Trap Program, by Chesley District Community School. For an interesting video of a pseudoscorpion hunting, click here.
