Hyalomma ticks prefer a more active hunting method. They ID you by your chemical scent, but they can also recognize a potential host visually from up to 30 feet away and will run along the ground to chase them down. The vibrations you cause as you walk and the heat from your body help Hyalomma ticks track you, too. They'll follow you for 10 minutes or even more, covering distances of up to about 325 feet. For reference, that's more than 15,380 body lengths for an unfed female —a 5'5" person would need to run nearly 190 miles to cover the same relative distance. But to be clear, Hyalomma ticks are not tiny: their bodies are around 0.256 inches long, which s about twice as large as most of the ticks you're used to. These guys really earn the nickname "giant ticks."
