Ticks 21 * |
These two North American ticks represent the Argasidae “soft ticks” (Lt), and the Ixodidae “hard ticks” (Rt).
Soft ticks, Argasidae, are oval or pear-shaped, with mouth parts that are more easily seen from the ventral view. Ixodes or “hard ticks” possess a dorsal plate or scutum, and many of them can transmit Lyme disease to humans.
