What makes the Seven-spotted Lady Beetle different from other species?
The Seven-spotted Lady Beetle has seven black spots arranged on a bright red wing cover, and a white or pale area behind the head with a dark border that looks like quotation marks. It is one of North Dakota's most common ladybugs, with over 228 iNaturalist records. The uniform spot pattern and classic red coloring make it easy to spot even for beginners.
How do you identify an Asian Lady Beetle in North Dakota?
The Asian Lady Beetle is also red or orange with black spots, but its key feature is a white or pale shield behind the head with a central black mark that resembles a wide M or W shape. These beetles are variable in color, some appearing almost yellow, and they can have as few as zero spots or as many as 15. With 211 records, they are nearly as common as Seven-spotted Lady Beetles in North Dakota.
Convergent Lady Beetle identification markers
The Convergent Lady Beetle is red or orange and smaller than the Seven-spotted, usually with 12 or 13 black spots in a regular arrangement. Its most distinctive feature is a white or pale band behind the head with two red or orange marks that converge upward, forming an inverted V shape. It ranks third in North Dakota records with 60 sightings.
What do the less common ladybugs look like in North Dakota?
The Spotted Pink Lady Beetle is pale pink or salmon-colored with black spots and a small size. The Parenthesis Lady Beetle has spots arranged in a pattern that resembles curved parentheses marks. The Thirteen-spotted Lady Beetle is smaller and often yellow with 13 spots, while the Fifteen-spotted is even smaller and pale. The Two-spotted Lady Beetle is solid red with only two spots. Together these species make up fewer than 100 records, so they are less frequently seen than the top three.
Body shape and size clues for ladybug identification
All North Dakota ladybugs are oval, rounded beetles with smooth shiny wing covers. Size ranges from 2 to 8 millimeters, with most species in the 3 to 5 millimeter range. The shell is hard and the underside is usually black or dark brown. If you spot a small red or orange beetle with black spots that fits this description, it is likely a ladybug rather than another type of beetle.
What is the pale area behind the ladybug's head called?
The pale area is called the pronotum, and its pattern is one of the most reliable identification features. The Seven-spotted has a white pronotum with black marks like quotation marks. The Asian Lady Beetle has a pronotum with a central black mark shaped like an M or W. The Convergent has a pronotum with two red marks forming a V. Using the pronotum pattern can quickly narrow down which species you have found.
When are North Dakota ladybugs most visible for identification?
Peak season is June through August, with June showing 106 records, July 103, and August 163 sightings. During these months, ladybugs are active in gardens, alfalfa fields, and on flowering plants where they hunt for aphids and other small prey. Spring and fall sightings drop to single or double digits, and winter records are very rare, with only one observation in December, January, and February.
Where should I look to identify ladybugs in North Dakota?
Ladybugs cluster on plants that host aphids, including clover, roses, corn, and prairie wildflowers. Look on the stems and undersides of leaves, and scan flowers from late morning through afternoon when they are most active. Alfalfa fields in the north-central and central parts of the state are productive spots, as are gardens and hedgerows with flowering plants.
