Antlion?

Mostly I'm just testing the 'upload video' feature since the quality of this video is a little terrible. While looking around to take pictures, I noticed several little pits and crouched down to see better. It turns out that there was a little beetle/bug trying to get out and towards the end of the video, you can see dirt being shoveled out while the beetle ends up getting flipped over several times.

I'm not sure what's going on here. Doesn't seem like the beetle is in any danger. I assume it's an Antlion since it's the only one I know that digs a pit.
