Twice-stabbed Lady Beetle

Chilocorus stigma, commonly known as the twice-stabbed ladybug, is a native resident of the United States and Canada. It also has been introduced to Hawaii. It is shiny black, and there is one red spot on each elytron. The remainder of the body is black as well, but the abdomen is either yellow or red. It is sometimes confused with the "two-stabbed lady beetle", Chilocorus orbus, which is widespread in California.
