Harmonia axyridis - Harlequin ladybird

French name:  Coccinelle asiatique
Dutch name: Veelkleurig aziatisch lieveheersbeestje
Family: Coccinellidae
Group: Arthropods
Origin: Asia
Habitat: terrestrial
Introduction:  biological control
ISEIA Score : 11
 
Naturalization in Belgium
First observation in the wild: 2000
Invasion stage: spread
Spatial distribution: widespread
Invasiveness
Reproduction in the wild: yes
Dispersion potential: high
Natural habitats: high
More on invasiveness: Lives in a very wide range of habitats: farmlands, orchards, wetlands, forest margins. Seems to avoid deep forest habitats.
Distribution in Belgium
Established populations
absent from district
isolated populations (1-5 localities per district)
widespread (>5 localities per district)

Impacts on Species
Predation / Herbivory: high
Competition: high
Disease transmission: low
Genetic effects: low
Impacts on Ecosystems
Nutrient cycling: low
Physical alteration: low
Natural successions: low
Food web alteration: likely
More on impacts: H. axyridis is a strong intraguild predator and is able to displace native ladybird species. Hence, population collapse of the two-spot ladybird Adalia bipunctata is largely attributable to its rapid expansion in North America and Europe. The arlequin ladybird is also known to invade houses in winter.
