The Polished Lady Beetle is native to the eastern United States. This species lacks spots on its wing covers, which can range from light red to orange. They are most common in Vermont during the summer months, peaking in July.
Not ranked in the United States, and species is listed as Apparently Secure in Ontario. Several studies indicate that the species may be in decline, which may be in part due to the introduction of non-native lady beetle species and in part due to land use changes.
The Polished Lady Beetle is one of three spotless Lady Beetle species in the United States. They are usually differentiated by geographic location and the markings on their pronotum (area directly behind their head).
Polished Lady Beetles can range from 3.7 to 5.7 mm in length.
