Status and distribution in Luxembourg

Distribution map of Cydalima perspectalis (Walker, 1859) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2020-01-23.

In 2007 the first specimen of the box tree moth was discovered in Germany. Due to transport of contaminated young box plants the species has spread across Europe in just nine years. 1

The first time the species occurred in Luxembourg was in 2015. On 11th September the first specimen of the box tree moth was found by Svenja Christian in Wasserbillig, municipality of Mertert (Hellers & Christian 2016). In 2016, the moth was observed in Dudelange by Georges Bechet.

The box tree moth is native to East Asia, where the caterpillars feed on Buxus microphylla without causing any damage. In Europe however,  the larvae of Cydalima perspectalis feed on the leaves of box trees (Buxus sempervirens). In addition, the species can attack the bark of the trees, causing them to dry out and die.
