Riccardoella limacum, a Common card

The card carries these facts from its Wikipedia article.

• Slug mites are very small, white, and can be seen to move very rapidly over the surface of their host, particularly under the shell rim and near the pulmonary aperture.
• While once thought to be benign mucophages, more recent studies have shown that they actually subsist on the host's blood, and may bore into the host's body to feed.
• Studies have shown that this species name has been frequently misapplied to the more widespread Riccardoella oudemansi, the white slug mite.
