Riccardoella limacum (Schrank, 1776)
|
Riccardoella limacum or the white snail mite is a member of the Acari (mite)[1] family which is parasitic primarily on snails. Slug mites are very small (less than 0.5 mm in length), 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,[2][3] 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. Despite its name, R. limacum is typically a restricted parasite of snails, while R. oudemansi is the common species on slugs, although it occasionally feeds on snails too.[4]
