This is not a scorpion

Something ran out from under a leaf. Tiny, like a springtail, but it didn't hop. Whenever I tried to pick it up with my skinny paintbrush, it raced backwards, as fast as it had been running forward.

Under a magnifying glass, it waved big, angular pincers at me, like a crab would. I captured it, finally, in a drop of water, then photographed it with the camera and the microscope.
