Trachypachus holmbergiDavid R. Maddison
Trachypachus holmbergi is found on loose loam or conifer duff. For example, specimens were common in one regularly-tilled garden at the University of Alberta, where they would run in the sunshine, and dive into soil to escape capture. They were found in a similar, but more natural habitat, at the base of a slope in Cape Perpetua, Oregon.
