Akiko Mizutani of Australian National  University in Canberra and her colleagues used stereo cameras to  precisely capture dragonfly flight maneuvers in three dimensions and  then reconstructed dragonfly-eye views of pursuers. Their results,  published in the June 5 <em>Nature,<\/em> show that a male dragonfly can adjust  its position relative to a rival so perfectly that its image always  appears on the same spot on the rival&#8217;s retina. This fools the rival  into thinking his pursuer isn&#8217;t moving, and can help the pursuer perform  sneak attacks. The researchers admit they&#8217;re not sure how the  dragonflies do the trick, which requires highly accurate flight control  and positional sensing. <\/span><\/p>\n<h6><em>This news brief appeared in the Random Data column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 6\/17\/2003.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Male dragonflies appear to be extraordinarily wily when in pursuit of rivals in their territories: they can fly in such a way that they appear completely motionless to their foes, a technique known as motion camouflage.
