A flattened, oval arachnid with mottled silvery markings that waits on grass tips and low brush for a passing host to climb aboard and attach.

Wood Tick
A flattened, ornately patterned tick that waits on low brush in the Rocky Mountain foothills, ready to grab onto large mammals passing within reach. Its mottled, shield-marked back makes it one of the more distinctive North American ticks to identify.

A stout, mottled brown-and-silver tick that waits on grass blades with its front legs outstretched, ready to latch onto a passing host.
arachnid
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.
arachnid
Brown Dog Tick
A uniformly reddish-brown tick with an elongated body, the brown dog tick is unusual among ticks for being able to complete its entire life cycle indoors around wherever dogs rest. It has spread to warm regions worldwide largely by traveling with its preferred host.
arachnid
Rocky Mountain Wood Tick
A robust, ornately patterned tick of the western mountains that clings to shrubs and grasses waiting to grab a passing mammal.
arachnid
