|A Texas click beetle (Alaus lusciosus).|
|The big spots on top of the beetle are not its real eyes.|
If you watch the slow-motion part of the video carefully, you can see that the 'jump' is not caused by the beetle snapping back against my hand (as I had initially thought). Instead, the beetle lifts its head away from my hand and then the rest of its body just pops into the air. The key to the click and jump is the spine that extends down from the underside of the head.
