This from Tree of Life: "Katydids are found on all continents except Antarctica and in an assortment of habitats from tropical forests (Heller 1995) and peat bogs (Vickery and Kevan 1985) to montane alpine zones 'far above the last outposts of trees'. Within these habitats, virtually all tettigoniids are associated with vegetation, particularly during inactive periods when the insects retreat into (or onto) leaves.
