Once again, I went off and forgot my bugs on a slide and let them almost dry out. Luckily, I found them just in time and rescued them. This time, I added a drop of water to the edge of the coverslip. Watch what happens as the water gets to them.
They are Habrotrochidae or Philodinidae, [thanks to PondWaterWorld for the ID].
