Status and distribution in Luxembourg

Distribution map of Harmonia axyridis (Pallas, 1773) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2019-12-13.

The harlequin ladybird was observed in Luxembourg for the first time on 18th September 2004 by Nico Schneider at Schleifmillen, municipality of Junglinster (Schneider & Loomans 2006). 61 observations are documented in the Recorder database (26/01/2018).

The establishment of the species appears to decrease the diversity of native Coccinellidae. Harmonia axyridis can also quickly become a human nuisance when it seeks shelter during the winter months and takes up residency in the walls and insulation of houses and other structures.

Risk assessment

ISEIA protocol: B3 (3+2+3+2) = Watch List (Ries et al. 2017: 68).
