 The parasitic wasp "Ixodiphagus hookeri" lays its eggs inside castor bean tick, though the castor bean tick is not "I. hookeri"'s sole host.The scientific name of the castor bean tick dates back to the starting point of zoological nomenclature, the 1758 tenth edition of Carl Linnaeus' "Systema Naturae", where it appeared as "Acarus ricinus".Pierre André Latreille split the new genus "Ixodes" from Linnaeus' "Acarus" (which at that time contained all known ticks and mites), and "I. ricinus" was chosen as the type species.
