18 Types of Ladybugs in Tennessee

Eight ladybug species have been documented in Tennessee through iNaturalist observations. Asian Lady Beetles are the most abundant, appearing in over 5,800 sightings. Seven-spotted Lady Beetles are the second most common at 1,350 observations, followed by Spotted Pink Lady Beetles with 619. Polished Lady Beetles, Squash Lady Beetles, Twenty-spotted Lady Beetles, Twice-stabbed Lady Beetles, and Convergent Lady Beetles round out the list with smaller but consistent populations. Each species has distinct markings and behaviors that make them identifiable in the field.

Asian Lady Beetles vary in color more than native species, ranging from yellow-orange to deep red. Most have a white or pale area on the pronotum (the area just behind the head) that resembles an 'M' or 'W' marking, though not all individuals show this clearly. They tend to be slightly larger and more flattened than some native ladybugs, and they often gather in groups. In Tennessee, this is the species you are most likely to encounter, especially during spring and summer in gardens, forests, and open areas.

Seven-spotted Lady Beetles are bright red with seven black spots arranged in a classic pattern, three on one wing cover, three on the other, and one shared on the center line. They have a black pronotum with two white or pale red spots. These ladybugs are slightly smaller and more rounded than Asian Lady Beetles. In Tennessee, they appear regularly but in much lower numbers than Asians, and they prefer similar habitats including gardens, meadows, and light woodlands.

Convergent Lady Beetles and Twice-stabbed Lady Beetles are the rarest types documented in the state, with only 113 and 122 observations respectively. Twenty-spotted Lady Beetles and Squash Lady Beetles are also less common, with around 130 and 140 sightings. These species do occur in Tennessee but are found in lower numbers compared to Asians and Seven-spotted types. If you spot one of these rarer species, it is worth noting the habitat and season for nature enthusiasts and citizen science projects.

Spotted Pink Lady Beetles are pale yellow or pink with dark spots, and they lack the strong red coloring of many other ladybugs. Their spots are arranged across the wing covers in a pattern that is less symmetrical than Seven-spotted beetles. With 619 documented sightings in Tennessee, they are moderately common and are often found in similar habitats to Asian and Seven-spotted types, particularly in cultivated areas and open woodlands during May and June.

May, April, and June are the peak months for ladybug activity in Tennessee, with May showing the highest sightings at over 1,530 observations. April follows at 1,307, and June at 1,287. Numbers drop as summer progresses, with August recording 740 sightings and September around 960. Activity remains steady through autumn and into early winter, though sightings are fewer from January through March. Spring is the ideal time to search for ladybugs in gardens, meadows, and forest edges where they hunt for aphids.

Ladybugs in Tennessee favor gardens with flowering plants and vegetation where aphids congregate. Open meadows and forest edges, particularly in the Great Smoky Mountains and Cumberland Plateau regions, are productive areas. They also gather on goldenrod, milkweed, and native shrubs. During spring and early summer, checking plants that are actively growing and showing insect activity will improve your odds of finding multiple species. At night, they shelter under bark, in leaf litter, and in protected spots to await the next foraging day.

Asian Lady Beetles are notably gregarious, often clustering in groups during migration and hibernation, while native species like Seven-spotted are more solitary or found in small groups. Native ladybugs tend to spend more time on plants hunting aphids and mating, whereas Asians may congregate in large numbers in fall, seeking shelter in structures or dense vegetation. Understanding these behavioral differences helps you predict where and when you might find each type. All species are predatory and beneficial, feeding on aphids, mites, and other small pests throughout their active season.

The Asian Lady Beetle is an introduced species from Asia that was released in North America as a biological control agent for aphids. It has become established across Tennessee and the entire continent. Native Tennessee species include the Seven-spotted (now also widespread across North America), Convergent, Twice-stabbed, Polished, Spotted Pink, Twenty-spotted, and Squash Lady Beetles. The presence of both native and introduced species in the state reflects decades of ecological change, but all ladybugs in Tennessee perform the same ecological role of consuming plant pests.

Rare species like Convergent, Twice-stabbed, Twenty-spotted, and Squash Lady Beetles are worth documenting. If you find one, photograph it with clear details of the markings, location, date, and habitat, then upload your observation to iNaturalist. The platform helps scientists track species distribution and abundance across regions. Your sighting contributes to our understanding of Tennessee's ladybug populations and may reveal patterns in habitat use or migration. Even common species benefit from detailed observation records.

Start by noting overall color, red, orange, yellow, or pale pink. Then count and examine the spot pattern. Red beetles with seven symmetrical black spots are almost certainly Seven-spotted Lady Beetles. Red or orange beetles with a white or pale 'M' or 'W' mark on the pronotum are likely Asian Lady Beetles. Pale yellow or pink beetles with scattered spots are probably Spotted Pink types. Use the size and shape as secondary clues. With practice, recognizing these three most common types will make you confident in identifying the majority of ladybugs you encounter in Tennessee.
