| ballistics and visual targeting in flea-beetles (alticinae) | the kinematics of jumping was measured in seven species of flea-beetle (alticinae). the accuracy of two species during targeted jumping was also investigated. take-off accelerations ranged from 15 to 270 times gravity. rotational energy accounted for 4­21 % of the total translational energy. two species were able to control jump direction and landing. when presented with a high-contrast optical grid, chalcoides aurata exhibited two alternative jump modes. in mode 1 or wingless jumping, the b ... | 1995 | 9319842 |
