Brief description

HarAxy ontwikkelingHarmonia axyridis (Pallas, 1773) lives in a very wide range of habitats: farmlands, orchards, wetlands, and forest margins. It seems to avoid deep forest habitats. H. axyridis is a strong intraguild predator and is able to displace native ladybird species, hence the population collapse of the two-spot ladybird Adalia bipunctata is largely attributable to its rapid expansion in North America and Europe. The Harlequin ladybird is also known to invade houses in winter (Adriaens et al. 2007).
