Our almond tree has dried. Bark is peeling off. Underneath the bark was this very tiny fellow, moving easily and equally quickly both forward and backward!! I thought this must be some nymph of some insect. Which one? Second photo.. finger for scale.
Tiny scorpion like insect... for ID
It's a pseudoscorpion, a non-venomous arachnid, distantly related to spiders and true scorpions. They are predators on other small invertebrates.
Oh Ed, how interesting... yes it is. But how big can it grow?
