I think this set of photos of a captive Cicindela larva lunging at prey can speak for itself:
I wanted to capture the amazing moment when a tiger beetle larva captures prey so I took my Canon 7D, set it to 720p, 60 fps in video mode, and waited for the larva to come to the burrow mouth. Once the larva was at the ready I dropped a small prey item, in this case a Red Flour beetle (larva and adult), and dropped it as close to the edge of the tube in which the larva was set up; this process was repeated twice. The strike at the prey was so fast only when the video was played back frame-by-frame was I able to see the process. For the video of each prey items I selected one frame from before the larva struck and one at the moment at the moment of the strike itself.
