These two clips depict a Bush Katydid (Scudderia species) living in Greenville County, South Carolina, USA. In the second clip, this katydid moved up to a higher position in the vegetation to take-off on a flight. Note the side-to-side movements of the katydid prior to take-off. This movement is thought to provide parallax (separation) to support estimation of the distance of the target position by the katydid.
