Lower subalpine dry meadow on bench above Fourmile Creek willow carr. 13S 490732 4303004 E 3139m (10,300') On Antennaria pulcherrima.

Short quick stop and go movements across the ~flat-topped inflorescence, changing direction abruptly after each stop. After several moves, repeatedly "walked" off the edge of the inflorescence to the underside and reemerged again on the upper surface after a few seconds.
