Summary

Chilocorus kuwanae, known as Kuwana's lady beetle, is a lady beetle species in the family Coccinellidae, introduced to North America for biological pest control. It is identified by its unique characteristics and life cycle focusing on scale insects, and has established a presence across the continent since its introduction.

Physical Characteristics

Length 3.0 to 4.75 mm, width 2.90 to 4.50 mm.

Identification Tips

Distinguished from similar native 'black with two red spots' Chilocorus species by three key differences.

Habitat

Arboreal, found in trees where scale insects are present.

Distribution

Introduced throughout North America, originally native to Europe, Northern Asia (excluding China), and Southern Asia.

Diet

Feeds primarily on scale insects, particularly armored scales.

Life Cycle

Eggs are laid singly under the hard 'shell' of a scale insect; larvae feed under the scales and develop long, protective spines as they mature. Pupation occurs inside the last larval 'skin' with adults emerging about a week later.

Reproduction

Eggs are laid under scale insects to protect them and provide food for larvae.

Ecosystem Role

Beneficial insect for biological pest control, targeting scale insects.

Evolution

Originally introduced from Japan and Korea; established in California and has spread throughout North America.
