20 Types of Ladybugs in Nevada

The Seven-spotted Lady Beetle leads with 716 iNaturalist observations across Nevada. Its name comes from the classic pattern of seven black spots on a bright red or orange wing cover, with a white mark on each side of the black head. This beetle is medium-sized, roughly 0.28 to 0.31 inches long. It thrives in gardens, meadows, and scrubland from spring through early fall, and is often the first species beginners learn to identify.

The Convergent Lady Beetle ranks second with 698 Nevada sightings. Look for a white pronotum (the section behind the head) with a distinctive black mark that resembles an upside-down V or two converging lines. The wing covers are typically red or orange with black spots that vary in number and arrangement. Adults are slightly smaller than Seven-spotted beetles, usually 0.24 to 0.35 inches. Convergent Lady Beetles are strong fliers and often gather in large swarms during fall and winter.

No, the Asian Lady Beetle is non-native to Nevada and North America as a whole, but it has established populations here. With 154 observations, it is the third most documented species in the state. These beetles are larger than native species, typically 0.28 to 0.39 inches, and variable in appearance, ranging from yellow to orange with zero to fifteen black spots. They may have a white or orange pronotum with black marks. Their mandibles and legs often appear more prominent than in native species.

Transverse Lady Beetles account for 125 Nevada sightings. These beetles have red wing covers with five or six black spots arranged in a characteristic transverse (across-the-body) pattern. They are medium-sized, around 0.25 to 0.31 inches long. The pronotum is typically white with a small central black mark. Transverse Lady Beetles prefer open, sunny habitats and are often seen on low vegetation and flowers during late spring and summer.

Yes, Ashy Gray Lady Beetles are present in Nevada with 105 documented observations. These beetles are distinctive for their gray to brownish coloration, quite different from the bright red of other species. They are small, typically 0.19 to 0.24 inches, and have a matte finish rather than a shiny appearance. Some individuals may show faint spots or patterns. They favor drier, more open habitats and are most active during spring and early summer.

Despite the name, Two-spotted Lady Beetles can vary in their spot count, and Nevada observers have recorded 81 sightings of this species. The typical form has two large black spots on bright red or orange wing covers, but some individuals lack spots entirely. These beetles are small, around 0.2 to 0.25 inches long, with a smooth, shiny appearance. They are adaptable beetles found in gardens, meadows, and disturbed areas from spring through fall.

Spotless Lady Beetles, with 61 Nevada observations, have uniformly solid red or orange wing covers with no black spots. They are small beetles, typically 0.19 to 0.26 inches in length. The pronotum is white or pale, usually unmarked. These beetles are less common than spotted species and often go unnoticed because their plain appearance makes them easy to overlook. They prefer shrubby and grassland habitats and are most active in spring.

Sinuate Lady Beetles represent the eighth most recorded species in Nevada, with 56 iNaturalist observations. The name refers to their sinuous, wavy spot patterns on red or orange wing covers. These beetles are small to medium-sized, around 0.22 to 0.30 inches long. The spots tend to be large and irregularly distributed, giving each beetle a somewhat unique appearance. Sinuate Lady Beetles are most active from April through June and prefer open meadows and grasslands.

Peak season runs from April through June, with June being the single busiest month for ladybug activity in Nevada. April and May also rank in the top three months for sightings. During this period, native plants and cultivated gardens are flowering, providing abundant aphids and other small insects that ladybugs hunt. Early morning visits to gardens, meadows, and sunny edges of sagebrush country offer the best odds of spotting multiple species in a short outing.

Size alone is not reliable for identification. While some species trend smaller (Ashy Gray at 0.19 to 0.24 inches) or larger (Asian Lady Beetle at 0.28 to 0.39 inches), there is significant overlap. The Seven-spotted and Convergent beetles, for example, are both in the 0.24 to 0.35 inch range. Always combine size with spot pattern, coloration, pronotum markings, and sheen (matte or glossy) for accurate identification. Digital photos taken in natural light help confirm identifications.
