I never knew about this until I read about it in a blog entry by E. H. Kern.

Now that I think about it, the best book ever involving eyelash mites is Jay Hosler’s Sandwalk Adventures, A wonderful look at Darwin and natural selection from the viewpoint of both Charles Darwin and a smart and engaging little eyelash mite.
