Argas
Bat-ticks
Argas is a genus of soft ticks in the family Argasidae, containing 44 species across two subgenera: Argas and Persicargas. These ticks lack the hard dorsal shield characteristic of hard ticks (Ixodidae) and exhibit distinctive feeding behaviors, taking multiple short blood meals rather than prolonged single feedings. The genus includes species with exceptional longevity—Argas brumpti individuals have survived 27 years in laboratory conditions and endured eight years without feeding. Argas species serve as vectors for tick-borne pathogens including those causing tick-borne relapsing fever.
