The Convergent Lady Beetle is native to North America. It feeds on aphids and other agricultural pests, making it common in agro-ecosystems. Although they can eat nectar and parts of plants, they will not reproduce unless there are aphids to feed on. Its number of spots can vary, however the maximum number is 13.



Ranked as Secure in British Columbia; Apparently Secure in Alberta, Saskatchewan, Ontario, and New Brunswick; and Vulnerable in Manitoba. The Convergent Lady Beetle has not been ranked in the United States.

Fun Fact

Convergent Lady Beetles will congregate along lake shores, especially in the spring and fall.


Slightly oblong in shape, 4 to 7 mm in length.


Habitat generalist, found everywhere from agricultural crops (wheat, sorghum, alfalfa, vegetables, orchard crops), to meadows, forests, and gardens. Plays a large role in agricultural pest control.

General Range

Southern Canada to South America.


Aphids. Will also eat small insect larvae, scale insects, insect eggs, and mites. Will sometimes consume nectar if prey is scarce or in the fall, before hibernation. Valuable as a pest control in agricultural crops.

Life Cycle

Lays eggs over a three month period, beginning in spring or early summer. The Larval stage lasts between 10 and 30 days, and then Convergent Lady Beetles will pupate for up to 12 days, depending on temperatures. They have one to two generations per year (one in early summer and one in fall), depending on the climate, then hibernate in groups under leaf litter, logs, ground vegetation, or in sheltered areas, occasionally invading people’s homes. They can most easily be found in early summer or in fall, before hibernation.

This is a common American Lady Beetle that is frequently sold for aphid control. It has a slight tolerance for some pesticides, if applied at the appropriate rates.
