Pseudoscorpion

Dear Shower Psycho,
You have discovered a Pseudoscorpion, a harmless arachnid that has no venom unlike its stinging namesake.  Pseudoscorpions are cosmopolitan in distribution and they are rarely noticed because of their tiny size.  They use their claws to capture prey, and they are beneficial predators.  They can also use their claws to attach themselves to larger flying insects that they use to transport them to new feeding grounds, a phenomenon known as phoresy.  Since it is the end of the month, we need to select a Bug of the Month for May, and we are choosing your submission.

    Is it possible that the Pseudoscorpion developes in a tube like chrysalis like a butterfly. I saw a black tube about 3/4 inch long hanging from a shrub on a spider like filament. There was one tint stick likr appendage with a scorpion like pincers at the end actinly opening and closing. This was this week in Port Townsend, WA. zip code 98368.

  2. I saw this week in Port Townsend, WA 98368 a strange inscet hanging from a shrub by a 3 inch filament. It was a black tube (about i1 inch long by 1/8 inch wide. From the top a slender arm like appendige that ended with a scorpion like claw. The claw was rpidly opening and closing. Do Pseudoscorpions develop this way/ If not I would appreciate help in identifying this creature.
