The bees I recently posted were washed in alcohol and then the alcohol was centrifuged to concentrate the "debris." The drop of "concentrated" alcohol was then put in a well slide and allowed to evaporate. In addition to a lot of pollen, I isolated the following mites.
I think if I mount the mites in the future with balsam and a cover slip I might get better results.
