Tick species identification

Rocky Mountain wood tick

What to look for

Brown with ornate pale markings; adults resemble American dog ticks, making geography and close dorsal photos important.

Known disease associations

  • — Rocky Mountain spotted fever
  • — Colorado tick fever
  • — Tularemia

Finding this species does not mean the tick carried a pathogen or that transmission occurred.

Photos need context

Feeding, life stage, image angle, and damage can change how a tick looks. A useful identification weighs several visible traits together and states uncertainty when the photo does not show enough detail.
