>Several times most of the cap was later removed leaving a neat oval
window; I always saw mites in those cells, and in at least one case the
workers reached in around the cocoon and caught the mite.

Thank you for these excellent observations Carolyn!  Since I began applying
strong selective pressure for mite resistance, I see more and more bald
brood.  I need to spend more time with observation hives!
