Species Spotlights

Different hosts and regions bring different tick lineups. Below are quick visual cues for the most common culprits you might encounter.

Dog Tick Identification

When your furry friend comes back from a hike, look for a brownish tick with a lightercolored dorsal shield and often three pairs of legs visible. The American dog tick (Dermacentor variabilis) typically has white festoons at the edge of the scutum.

Deer Tick Identification

Also known as the blacklegged tick, its smallabout the size of a grain of sand when unfed. Its scutum is a dark brown oval, and the legs are noticeably black. This is the species most associated with Lyme disease.

Human Tick Photo Tips

If you need a picture of a tick on a human, gently lift the tick with tweezers, place it on a piece of clear tape over a white card, and photograph. Capture both the whole tick and a closeup of the mouthpartsthis helps experts differentiate between a deer tick and a dog tick.

Next Steps After ID

Once you receive a species name, its time to act based on the associated disease risk.

If Its a BlackLegged (Deer) Tick

These ticks can carry Lyme disease, Anaplasmosis, and Babesiosis. Watch for a bullseye rash, fever, chills, or joint pain over the next few weeks. If any symptoms appear, see a doctor promptly and mention the tick species.

If Its an American Dog Tick

They are vectors for RockyMountain spotted fever and tularemia. Symptoms often include sudden fever and a rash that starts on the wrists and ankles. Again, early medical attention is key.

Inconclusive or Uncertain Results

When the ID service says inconclusive, dont panic. Collect the tick in a sealed plastic bag with a damp paper towel, label it, and send it to a state lab for DNA testing. Keeping the specimen intact preserves the chance for a definitive answer.

• The Centers for Disease Control and Prevention (CDC) their tickborne disease overview offers uptodate prevalence maps and symptom checklists.
• University entomology departments (e.g., University of Rhode Island, Michigan State University) they publish peerreviewed identification charts and seasonal tick activity reports.
• State health departments their local tick identification portals reflect the species actually found in your area, ensuring the best match.

When you reference these sources in your own notes, add proper citations (author, year, URL) to keep your information transparent and credible.
