Halmus chalybeus, commonly known as the steelblue ladybird, is a species of ladybird (the beetle family Coccinellidae). It has an iridescent blue/green colouration and is a predator of other insects. It was introduced to New Zealand from Australia in 1899 and 1905 to control black scale and blue gum scale (see scale insect) on citrus trees,[2][3] where it is now common in northern regions.[4] It has also been recorded eating San Jose scale.[3] They are about 3-4 mm long.[2]
