Day 49 of our captivity: Very small bug

I saw Chad messing around with his lUSB microscope this afternoon and cast about the kitchen for something interesting to look at, settling on a potato that had gone green that we are waiting to sprout enough to plant.  We did get a good look at the burgeoning microsprout, which looks oddly like a molar at this point, and also discovered a very tiny dead bug that one would never have known was there.

For reference, here is the same potato in my hand.  One clearly eats these little tiny bugs *all the time* without knowing it.
