A recent addition to the Belgian list (2010), first recorded in our country as larvae, imported with Buxus in a retail trade at Ekeren (AN). About 2 months later the first imago was trapped in LI. This pest species is an introduction to Europe with imported Buxus plants. First observation for Europe was in 2006 in Germany followed by Switserland (2007), Austria, England, Netherlands and France in 2008. Nowadays (2018) it is a very common species in Belgium, although in the southern part it is rather rare.
Invasive In Belgium since May 2010.
Caterpillars were introduced with some imported plants. The species spread very rapidly and it destroys the larval hostplant.
The moths hide during day time, but they fly at dusk and throughout the whole night. They come to light.
The adults fly in two or three generations a year with the first imago's appearing during April/May towards September. When conditions are right, more generations appear and small numbers can be observed until late in October.
