This is a small black ladybeetle with two reddish spots on the elytra. It occurs also in Hawaii where it was introduced from the Philippines. We found it in many places, and apparently it was responsible for the scarcity of the mealybug Ferrisia virgata, as it was found associated with it as well as with other mealybugs.
