The fairly large white and brown-bordered adult moths are unmistakable. Please note a purple-brown melanic form is also common. Larvae cause severe damage to Box.

The moth is considered a pest species of Box (Buxus) in many European countries. Records in the UK are thought to be by accidental importation in Box plants from Asia.

The first UK record of this Asian species was from Kent in 2007. Since then there have been a number of records from several counties and is spreading rapidly across the UK.
