Common NameNine-spot Ladybug (or Nine-spotted Ladybug)
SeasonalityIt has two generations in one summer. But unlike C. septempunctata there are no indications of overlap. The spring generation goes into diapause due to the increasing day length in summer and the summer generation goes into diapause due to decreasing day length in fall (Acorn, 2007).
Identification4.0-7.0 mm long. A pale orange, rounded ladybug with nine black spots on the wing cover. Narrow black pigment where the wing cover meets, a feature that helps distinguish it from seven-spot ladybug (Acorn, 2007; Belicek, 1976). It also has spotless forms that can be confused with other spotless ladybugs. In that situation it is best to use the colouration and patterns on the head. It exhibits no sexual dimorphism (ADW, 2012).
