Summary
The Argasidae family consists of soft ticks, known for their oval or pear-shaped bodies and the positioning of their mouthparts. With around 193 species in five genera, they are prevalent in South Asia and adapted to survive in various climatic conditions.
Physical Characteristics
Soft ticks lack the hard scutum present in hard ticks (Ixodidae). The body is oval to pear-shaped, rounded anteriorly, and the lateral edges are rounded. The mouthparts are located on the underside of the body, making them less visible compared to hard ticks where the gnathosoma projects forward.
Identification Tips
Look for the absence of a hard scutum and check the underside of the tick for visible mouthparts. The rounded body shape and lateral edges are distinguishing features of soft ticks.
Habitat
Soft ticks are commonly found in various habitats, especially in regions with humid or arid conditions where they can survive for several years.
Distribution
They are particularly common in South Asia, contributing to the high biodiversity of ticks in this region, which includes about 97 species of ticks known to exist there.
Diet
Soft ticks are ectoparasites that feed on the blood of their hosts, which can include birds, mammals, and other vertebrates.
Life Cycle
The life cycle of soft ticks generally involves larval, nymphal, and adult stages, with multiple nymphal instars possible before reaching maturity.
Reproduction
Soft ticks typically reproduce by laying eggs, which hatch into larvae that will eventually transition into nymphs and then adults.
Ecosystem Role
Soft ticks play a role in ecosystems as ectoparasites, affecting host populations and contributing to the food web.

Misconceptions
A common misconception is that all ticks are hard ticks; soft ticks, which are distinct in body structure and ecology, are often overlooked.
