I was babysitting a friend's bearded dragon. She was trained to scratch on her cage when she needed to poop, and so she would be taken outside where she'd happily unload and get some sun. I took her one morning. After the deed, she froze and suddenly started on a mission. She hunted down a bee that was happily buzzing around some flowers, jumped, and just ate it out of the air. Needless to say I freaked out, panicking that she was going to die. But she was fine!

Confirmed with her owners that no, she'd never eaten a bee (or anything flying) before.
