Lone Star Tick
Named for the single silvery-white spot on the back of the adult female, the lone star tick is unusually active for a tick, moving toward hosts rather than simply waiting for them to pass. Its reddish-brown, ornamented body makes it one of the easier North American ticks to identify at a glance.
