Size matters!

Size matters! If the pony was the size of a beetle - that would be an easy keeper! If the beetle was the size of a pony, I would saddle him and fly! (actual size of my latest mud pony and Palo Verde Root borer, no photo montage. The stuff to do when it's too cold to go 'bugging') Actually - if a homoiotherm animal like a pony was that small, it would have to live on a high caloric diet and eat constantly, more so than a hummingbird. So no easy keeper at all. And a huge, rideable beetle would suffer from oxygen deprivation even at ground level, much less high up in the air. Bummer!
