In this colorized image taken via low-temperature scanning electron microscope, a Varroa mite’s impression left on the abdominal wall of a honey bee is visible. White arrows identify foot pads of the mite that remained attached following removal of the mite. The black arrow identifies the mite’s feeding site.
