Macrohabitat: Lowlands to midlands, sea level- 1045 meters altitude. Microhabitat: "At Moolack Beach along the coast of Oregon, Trachypachus slevini can be found running on the cliff above the sandy beach of the Pacific Ocean. The beetles run in the talus slope, consisting of small particles, at the base of the cliff of exfoliating clay. The beetles run along for a short way in the sunshine, then dive into the pile of debris; they are also found higher up on the cliff on the hard clay." Maddison (2001). Dispersal abilities: Macropterous, and these no doubt functional. Seasonal occurrence: Adults have been found in July- October. Behavior: Adults take cover under debris on the ground.
