8 Types of Ladybugs in South Dakota
Yes, eight species of ladybugs are documented in South Dakota, with the Asian Lady Beetle and Convergent Lady Beetle accounting for the vast majority of sightings. Most are present year-round, but June through August bring the highest counts. Learning to identify these species helps you understand which are native, which arrived more recently, and what habitats support each type. The field marks differ by size, spots, color, and the distinctive pronotum (the area behind the head). Start with the most common species and work down to the rarer records.

What is the most common ladybug in South Dakota?
The Asian Lady Beetle (Harmonia axyridis) dominates South Dakota ladybug sightings, with 490 documented observations out of 1,173 total records. It was introduced to North America as a biological control agent and has since become the most abundant lady beetle across much of the continent. It ranges from pale yellow-orange to deep red, with spot counts varying from 0 to 15 per wing cover. Look for a distinctive white pronotum with two dark spots or markings. Asian Lady Beetles are highly adaptable and thrive in agricultural, urban, and wild habitats. They are most commonly observed from June to August but can be found in every month.
Convergent Lady Beetle identification
The Convergent Lady Beetle (Hippodamia convergens) is the second most recorded ladybug in South Dakota with 222 observations. It is native to North America and has been commercially bred as a beneficial insect for decades. The species name refers to the white pronotum, which has two curved converging lines that point inward, creating a distinctive V-shape or convergent pattern. The wing covers are typically bright red or orange with 13 black spots arranged in a regular pattern. Convergent Lady Beetles are slightly smaller than Asian Lady Beetles and prefer agricultural and garden settings where aphids are abundant. They appear most frequently in spring and summer.
How to tell the Seven-spotted Lady Beetle apart
The Seven-spotted Lady Beetle (Coccinella septempunctata) was introduced to North America and represents 174 sightings in South Dakota, making it the third most common species. It is more distinctive than the Convergent Lady Beetle due to its deep red wing covers and exactly seven black spots arranged in a specific pattern: four on the left wing cover, three on the right, plus one spot in the center. The pronotum is white with two black spots. It is slightly larger and rounder than many other species. The bold, regular spot pattern makes it unmistakable once you learn the layout. Peak observations occur in summer months.
Spotted Pink Lady Beetle and Eye-spotted Lady Beetle
The Spotted Pink Lady Beetle (Coleomegilla maculata) accounts for 63 observations in South Dakota. It is distinguished by a pale pink or orange-red background with larger, black spots and a white pronotum often with red centers or markings. The Eye-spotted Lady Beetle (Propylea quatuordecimpunctata) has 51 records and is smaller and more elongated than typical ladybugs, with 14 small black spots on a red background and a distinctive white pronotum bearing a dark spot that resembles an eye. Both species are native to North America and prefer cooler seasons, with higher counts in spring and fall compared to summer.
Less common species in South Dakota
The Parenthesis Lady Beetle (Hippodamia parenthesis) appears in 19 observations and resembles the Convergent Lady Beetle but has a slightly different pronotum marking that resembles a parenthesis or bracket rather than a converging V. The Nine-spotted Lady Beetle (Coccinella novemnotata) is recorded only 8 times and is considered native but now rare in much of the United States due to competition with introduced species. The Ursine Spurleg (Propylea ursina) has 13 sightings and is a small species with distinctive short legs and body proportions that set it apart from larger coccinellids. These rarer species are worth documenting if you encounter them.
When do South Dakota ladybugs reach peak numbers?
June, July, and August are the months with the highest ladybug activity in South Dakota, accounting for 635 observations across all species combined. June shows 271 records, July has 227, and August reaches 137. This summer peak corresponds to the season of highest aphid abundance, which drives the reproductive cycles and host-seeking behavior of all ladybug species. Spring and early fall also support good populations, with April showing 107 observations and May with 118. Winter months see far fewer sightings, with January at 10 and December at only 8 records, indicating that most ladybugs either leave the state, hide dormantly, or aggregate in sheltered sites.
What habitats attract different ladybug species?
Asian Lady Beetles and Convergent Lady Beetles favor agricultural fields, crop edges, and managed gardens where aphids cluster on cultivated plants. They are highly visible on canola, soybeans, and small grains. Seven-spotted Lady Beetles also thrive in agricultural settings but show a slight preference for cooler, northern regions. Native species such as the Spotted Pink Lady Beetle and Eye-spotted Lady Beetle prefer wild flowering plants, tree bark, and meadow vegetation where they hunt smaller prey like scale insects and mites. All species need access to water and shelter from wind and extreme temperatures. Mixed landscapes with both crops and uncultivated margins support the widest diversity.
Do native and introduced ladybug species compete in South Dakota?
Yes, the dominance of introduced species like the Asian Lady Beetle and Seven-spotted Lady Beetle has contributed to the rarity of some native species, including the Nine-spotted Lady Beetle. Competition for food (aphids and other small arthropods) and habitat occurs, though the exact mechanisms are still studied. The Spotted Pink Lady Beetle and Eye-spotted Lady Beetle persist in South Dakota, likely because they occupy different microhabitats and hunt different prey than the most abundant introduced species. Protecting a diversity of plant communities and avoiding broad pesticide use supports coexistence. Native species are still worth documenting and protecting, especially the Nine-spotted Lady Beetle, which was once widespread across North America.
How to photograph and report your ladybug sightings
If you observe a ladybug you want to identify and share, take a clear photo showing the pronotum (white area behind the head), the spot pattern on the wing covers, and overall body shape. Include a reference object such as a leaf or pencil tip for scale. Upload your observation to iNaturalist (iNaturalist.org) where community experts can confirm the species and your record contributes to the South Dakota ladybug database. Include the date, location, and habitat notes if possible. iNaturalist observations feed directly into research projects and inform scientists about species distribution and phenology. Your sighting helps document which ladybug species are thriving in specific areas of South Dakota.
