One day I think I would like to try keeping one because they're cute.
The thing I would dread the most though, is if they started flying...
I heard that they don't really like to fly because it's very energy-intensive for them, but still.
I'm glad I wouldn't have to feed them any sort of other bugs, though - they're herbivores, and you feed them special jelly!
No, not at all. I'm absolutely terrified of bugs so I don't think that I'd keep them. Also after reading that they can fly in Airy's comment, I would hate to keep them as a pet. Howeverrr, I think that it is pretty awesome that you collect beetles, not many people I have come across have had such an interesting hobby as you do!
Personally, I'm more of a dog-person (though my parents won't allow me to get one).
