Cydalima perspectalis (Walker, 1859) Species

Last modified: Jan. 19, 2022, 12:52 p.m.

First recorded in Belgium in 2010 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. Since 2015 it is a very common to abundant species in Belgium, although in the southern part it is still rather rare.
