Pseudoscorpions are tiny, venomous critters that barely reach 4mm in length (not counting those pincers). They have no tails, and instead have venom in their pincers that they use to subdue their prey. This little guy was fully grown at 4mm. Though they have “scorpion” in their name and I have mentioned twice now that they are venomous, pseudoscorpions are completely harmless to humans. If you find them in your house or garden, leave them be–they’re death on nuisance bugs. Aphids, for example, should take a much more concerned view of pseudoscorpions.
Did you know that pseudoscorpions are big supporters of public transit? Whole packs of them will change foraging areas by finding a large beetle or grasshopper and climbing aboard. They snuggle up underneath the wings and huddle together, waiting for the “bus” to carry them to new hunting grounds.
