The c-7, or seven-spotted ladybeetle, is originally from Europe and was introduced to the United States for aphid management.

The adults and larvae can be found in a variety of habitats, wherever aphids occur in larger numbers.

Identification

Adults

Round, concave on top, flat underneath. Small, clubbed antennae. Two small white spots on head, seven black spots on a reddish-orange wings covers.

Larvae

Spiny alligator-like bodies with two incomplete orange stripes across a blue-black abdomen. Legs that appear sharp and footless at the ends.

Value in Pest Management

Important contributors to pest management. Although these non-native beetles focus their attention on aphids, they are generalist predators and will consume other small insects and their eggs. The natural control they provide helps to suppress some pest populations. They are also the most widely sold ladybeetle for biological control of insect pests in North America (see BIRC online Directory).

Origin and Distribution

Native, throughout North America.
