Variable Ladybird

Orange spotless ladybug. Thought before that it was Harmonia axyridis, but H. axyridis has white pronotum. Another spotless beetle, Cycloneda munda, has black pronotum. A ladybird from Australia, Chilocorus circumdatus, is bright orange in color but with dark edges on the helmet-shaped wing-covers base. This spotting has orange elytra without black edges and orange pronotum.

Nov 20, 2012 update - found out that this is a form of Coelophora inaequalis, the Variable Ladybird. - http://www.meloidae.com/en/albums/coelophora-inaequalis/.
