The Spotted Lady Beetle (also known as the Spotted Pink Lady Beetle) is an oblong, pinkish-red lady beetle with a total of twelve black spots on its wing covers. This beetle is native to North America and commonly feeds on aphids, other insect species, and pollen. They are most commonly found among crops that support aphid populations and are most abundant in September.

Status

Native

Conservation status has not been determined in the United States. In Ontario, Canada, Spotted Lady Beetles are considered “Apparently Secure:” at low risk of extinction or population collapse.

Fun Fact

At least one study has shown that planting flowers among aphid-susceptible crops reduces pest density because Spotted Lady Beetles attracted by the flowers’ pollen will also feed on the nearby aphids.

Identification

Habitat

Eats pests and pollen from crops. Frequently visits crops such as wheat, sorghum, alfalfa, soybeans, cotton, potatoes, corn, peas, beans, tomatoes, apples, and other crops attacked by aphids.

General Range

North to Southern Ontario and New England, south throughout the U.S. southern states and west into mid-western states.

Food

Aphids, mites, insect eggs, small larvae, and plant pollen, which may constitute up to 50 percent of their diet. The high percentage of plant pollen in the Spotted Lady Beetle diet is uncommon among lady beetles.

Life cycle

Spotted Lady Beetles can be found from April to October in Vermont. Females lay from 200 to over 1,000 eggs over a one to three month period, beginning in spring or early summer. Spotted Lady Beetles may be the most abundant in September and October as the adults aggregate for mating and preparation for winter hibernation. Spotted Lady Beetles overwinter in aggregations under rocks and leaf litter along hedgerows and protected sites, particularly near crops and other habitats they utilize.
