Oh no, Delphastus can fly!

On the hibiscus it's been easy to spot a few Delphasti (?) with little trouble so I retain hope they may yet work against our mutual enemy, the accursed whitefly. But this morning during inspection one of the little black beetles took to flight! Not that there isn't plenty of other food available but I'm more worried about the predator side of the Magic Bulb-osystem.

I'd probably need to dump a thousand or so to hope for a colony to setup, like ladybugs. Or confine them to an aquarium type bug-making machine. Where do you go to get those?
