Lyme Disease : Soft Ticks / Hard Ticks

This drawing shows the morphologic differences between soft ticks, Argasidae, and hard ticks, Ixodidae. The soft ticks are oval, i.e., pear-shaped, and are rounded anteriorly, with mouth parts that are more easily seen from the ventral view. Some soft ticks are known to be a vector for the spirochetes responsible for causing “Relapsing Fever."
