Both the common name and the species name refer to the six small white spots on the beetle’s metallic-green to metallic-blue-green elytra. This is not always the case, however, as some individuals may have more spots, fewer spots, or none at all, presumably due to genetic variation.
Not saying you are wrong.
But this one has eight spots. Did the bug do it to thwart those naming and categorization efforts?
