Its head and pronotum are black with small white patches, giving it a clean and striking appearance. Adults measure about 7 to 8 millimeters long, with a slightly oval, dome-shaped body that gleams under sunlight.
This ladybug is native to Europe but was introduced to North America in the mid-20th century as a natural aphid predator. In Ohio, it has become naturalized and thrives in gardens, fields, and urban landscapes. The species is especially abundant in spring and early summer when aphid populations surge. They are frequently seen crawling on crop plants, ornamental shrubs, and flowering stems where their prey congregates.
As voracious feeders, Seven-Spotted Ladybugs primarily consume aphids but also eat scale insects and mite eggs. Both larvae and adults feed actively, making them valuable allies for farmers and gardeners. Their feeding behavior helps reduce the need for chemical pesticides, particularly in soybeans, cornfields, and vegetable gardens.
These ladybugs overwinter as adults, often sheltering beneath leaf litter, bark, or in protected crevices. When temperatures rise, they reemerge to mate and lay clusters of yellow eggs near aphid colonies. Their life cycle contributes significantly to pest management across Ohio’s agricultural landscapes.
Convergent Lady Beetle (Hippodamia convergens)
The Convergent Lady Beetle is native to North America and one of the most beneficial species in Ohio. It is distinguished by its orange-red elytra adorned with 13 small black spots, though some individuals may have fewer. The most distinctive marking is the pair of white lines on the pronotum that converge toward the head, forming a “V” shape. Adults are about 5 to 7 millimeters long with slender, oval bodies and delicate legs that allow them to move swiftly across foliage.
This species inhabits meadows, gardens, and farmlands throughout Ohio. It is especially abundant during spring and summer when aphid populations peak. The Convergent Lady Beetle is a key biological control agent and has been commercially reared for release in agricultural systems due to its effectiveness in controlling aphids, scale insects, and whiteflies.
Their diet consists almost entirely of soft-bodied insects, particularly aphids, which they consume in large numbers daily. Both larvae and adults are predatory, with larvae having elongated, alligator-like bodies covered in dark coloration and orange markings. These larvae can eat hundreds of aphids before pupating into adults.
In Ohio’s colder months, Convergent Lady Beetles overwinter in large aggregations beneath bark, leaf litter, or rocks. These groups can contain thousands of individuals, conserving warmth and moisture until spring. Once temperatures rise, they disperse to breed and continue their ecological role as natural pest controllers.
Asian Lady Beetle (Harmonia axyridis)
The Asian Lady Beetle, originally introduced from Asia for pest control, is now one of the most widespread ladybug species in Ohio. It is highly variable in color, ranging from pale orange to deep red, and may have many spots, few, or none at all. The most consistent identifying feature is the black “M” or “W”-shaped marking behind the head on its white pronotum.
