Say hello to Orcus chalybeus (Halmus chalybeus), and yes, it is a ladybug... except ladybugs aren't really bugs, they're beetles. This gem of a beetle's common name is the Steelblue lady beetle. Who needs spots when you have a color like that? This beetle came to Hawaii from its native Australia, and like some of the other Coccinellidae, it is valuable for its predation of pests such as mites, aphids and scale insects. I have seen them come to the rescue of my hibiscus plants. That's a big job for a little beetle - these guys are just a few (3-4) millimeters in length. That's about half the width of your pinky nail.
Just what makes a beetle different from a bug? Well for starters, beetles have two pairs of wings (as do all winged insects), but the outer wings are hardened, protecting the more fragile flying wings that are tucked underneath. Secondly, the mouth of beetles is different from those of bugs. Beetles are chewers while true bugs prefer to pierce and suck. Yup. So remember not to bug the beetle.
