Multicolored Asian Lady Beetle Harmonia axyridis (Pallas, 1773)Non-native  -  Invasive    Synonyms: Asian Lady Beetle, Halloween Lady Beetle, Harlequin Ladybird, Japanese Ladybug.
Kingdom Animalia   >   Phylum Arthropoda   >   Class Insecta   >   Order Coleoptera   >   Family Coccinellidae   >   Genus Harmonia   

Status:

Introduced from eastern Asia to control aphids and other agricultural pests and now abundant in our region. Our most frequently encountered ladybug. Often hibernates in homes and other buildings.

Description:

Extremely variable in appearance. Color ranges from orange to red. May have many to no spots. Note very squared "shoulders" of elytra.

Relationships:

Preys on aphids, mites, and scale insects. This non-native species' abundance is certainly impacting native ladybugs numbers and diversity. Host to the ectoparasite fungus Hesperomyces harmoniae.

There are 1,020 records in the project database.
